15 ZeRTO Ltd Answer Examples
1.
What do you feel are the primary features and benefits of the Java programming language?
As a company that utilizes Java, ZeRTO Ltd and your interviewer want to make sure that you have an understanding of the Java programming language and they do so by asking this question. Obviously a language packed with unique features, talk about the features that you can speak the most knowledgeably about and tie your direct experience to.

Ryan's Answer
"When I started working with Java three years ago, the first huge benefit was the fact that the Java syntax was based on C++. At that time, I had a great working knowledge of C++ and my transition to Java was absolutely seamless. The other amazing feature that I've come to appreciate with Java is how robust the memory management is in exception handling and automatic garbage collection."
2.
Do you have experience working with different CASE tools? If so, what do you have experience with?
The world of software engineering has greatly benefited from advancements in computer aided software engineering tools. Because ZeRTO Ltd is at the forefront of the industry, your interviewer will be looking to hear which tools you have experience with. Make sure not to concern yourself with providing a correct answer here, but rather focus on your flexibility to learn new aides when needed while explaining what you have experience with.

Ryan's Answer #1
"In my current role, I regularly utilize both diagramming and web development tools. The diagram tools assist our software projects by outlining the system data and components in a graphical form for us and this saves us a great amount of time while also being very reliable. The web development tools greatly help me visualize site changes that I am making because I don't have a deep background in web development. If hired for this position, I'd look forward to learning other CASE tools for prototyping, quality assurance and maintenance."
Ryan's Answer #2
"During my career and in my experience with CASE tools, most of my experience is in the lower CASE elements that focus on coding and testing the software after initial development. CASE tools have certainly made life as a software engineer more efficient and effective and I'd look forward to learn any new CASE tools if hired for this position here at ZeRTO Ltd."
3.
The next cloud engineer that we hire here at ZeRTO Ltd needs to be able build a system that can handle a high amount of traffic. How would you test our system's ability to handle large amounts of traffic?
This question allows your interviewer to gain insight into your thought process and ability surrounding building a cloud network that has an architecture that can handle large amounts of traffic without failure. Some key points to focus on your answer are your ability to match capacity to system demand and use horizontal scaling in the design of the system.

Ryan's Answer #1
"Cloud computing has certainly revolutionized the storage of high amounts of data and a key piece that cloud based systems bring to the table are their elasticity for handling large amounts of traffic. I see my job as building a cloud based system to scale horizontally to be able to handle the most data and traffic possible. To test systems, I've used a few different tools that were all very accurate prior to go-live."
Ryan's Answer #2
"In my current position as a cloud engineer, I have utilized internet scale services like Amazon S3 and Elastic Load Balancing to ensure that our cloud systems could handle large volume that fluctuate seasonally. Because of the great functionality of the internet scale services, internal testing wasn't necessary as we knew we were in good hands through those services."
4.
If you were asked to review a colleague's code that they had written, what key things would you look for?
For this question, your interviewer will obviously be looking to hear that you have adequate knowledge when it comes to coding processes. But most importantly, your interviewer will be looking to gauge your ability to be a team player and focus on the bigger picture when working on a project. In your answer, focus on your attention to detail and your ability to help others when needed.

Ryan's Answer #1
"As an experienced software engineer, I fully expect my colleagues to reach out to me for my insight and I never hesitate to provide open and honest feedback. When asked to do this, my main focus is ensuring that the code is readable and functional. If there are lines of code that need to be removed, I don't hesitate to let my colleague know that while also giving them feedback on why I feel it is unnecessary."
Ryan's Answer #2
"When I'm asked to do this in my current position, my main focus is on regulatory requirements that were put in place for the project and security issues. I work with a team of great engineers that are very efficient coders and these two areas are most often overlooked."
5.
Do you consider yourself stronger in C++, C#, Java, or Python?
Before your interview, do some research to understand what tech stack ZeRTO Ltd uses so you can best prepare and highlight your expertise. If you aren't as strong in one of the skills you feel is necessary, be sure to explain how you've used it and how you are growing your knowledge to become better. Be sure to be honest in your answer, as the company will likely test your strengths.

Ryan's Answer #1
"In my last company, we had a bit of an outdated tech stack and used C# and .NET. I found myself fully immersed in those technologies, but had a strong desire to learn more and become more familiar with modern technologies and how I can apply that in my career. That's what has me so interested in this role. Over the last year, I've taken courses in Java and C++, which I noticed you prefer. I've become proficient in the skills and in side projects, applied my increasingly strong knowledge. I'm probably strongest professionally in C# as that has been where my experience lies, but my passion and dedication is on the Java and C++ side, as I feel that's the more modern alternative. I'm excited about the possibility of applying that knowledge in a role at ZeRTO Ltd."
Ryan's Answer #2
"I am motivated and excited about this new opportunity because it will challenge me to grow in my (X) skills. I love soccer and enjoy spending time with my teammates. I am interested in continuing my education by studying (Y) to further my career."
6.
Discuss a couple of software sales techniques. Which sales technique do you think is most effective for ZeRTO Ltd, and why?
The interviewer would like to see that you have researched ZeRTO Ltd, putting some thought into the most significant selling features of their products and services. When it comes to software sales closing techniques, you could:

- Offer a short trial for free
- Have a great email marketing campaign showing off the features of your software
- Give product or software demos, but keep the short
- Sell pre-paid annual memberships

Perhaps you have some ideas of your own! Discuss which selling options you think would be the best fit for what ZeRTO Ltd is offering. Be ready to support your answer with facts.

Ryan's Answer #1
"I recently read that free trial offers can increase conversions by up to 25% and, because, ZeRTO Ltd has a straightforward product, I believe it would be very effective to allow people to try it for free for 14 days. The prospective customer would quickly see that it's simple to navigate and incredibly helpful."
Ryan's Answer #2
"Since there are so many customizable features that come with your product, I feel that the best sales technique would be a free 30-minute demo, followed up with a short trial period. I think it would be important for prospective customers to see the product in action, and how it would work for them, specifically."
7.
What programming languages would you consider yourself fluent in?
While this question gives your interviewer insight into the diversity of your programming language experience, they most importantly want to know that you are adaptable and able to learn on the fly if needed. Talk about the different languages that you consider yourself fluent in and, if possible, do as much research into ZeRTO Ltd as you can prior to your interview and try to speak to the specific languages that they work with.

Ryan's Answer #1
"From the start of college, where software engineering grew into a passion for me, I've become very fluent in Java, JavaScript and C++. My current role has me working primarily with C++, but I pride myself on my ability and passion to learn new programming languages and would be able to do so if hired for this role with ZeRTO Ltd."
Ryan's Answer #2
"During my training to be an engineer and then in my current role since graduating, a majority of my experience falls within Python. My current role delves deeply into artificial intelligence and Python is awesome with this advanced technology. As I understand it from talking to another engineer here at ZeRTO Ltd, a requirement would be for me to learn Scala. Though I haven't worked directly with Scala, I believe my experience and willingness to learn would have me up and running in no time if hired for this role."
8.
Here at ZeRTO Ltd, we strive for continuous delivery and continuous deployment with our software. Are you familiar with these processes in your current work?
In the industries that ZeRTO Ltd works in, updates to software are vital to end users for them to stay at the forefront of their business. To ensure that updates happen as quick and smoothly as possible, ZeRTO Ltd utilizes continuous delivery and continuous deployment for their customers. For this question, talk about what you know about these processes as a software architect, why they are important and what experience you have with them.

Ryan's Answer #1
"In my current role, we utilize a 100% continuous deployment process with our end users when we role out new changes to existing software. We use automated testing in our process to validate that code changes are correct and able to be deployed without issue. Once validated, changes are automatically rolled out to our end users. Having once utilized a continuous delivery system, I am very appreciative of working in an environment utilizing continuous deployment as it negates any need for human intervention in the roll out."
Ryan's Answer #2
"In my current position, we've slowly grown from a continuous integration process to a continuous delivery process. I love the automated testing process when we are looking at rolling out new changes to existing software and my role as the architect for our projects puts me in the drivers seat for sending out these changes. If hired for this role here at ZeRTO Ltd, I'd be very intrigued at learning and working with continuous deployment practices as well."
9.
Do you have experience working with data in a cloud computing environment?
Over recent years, more and more companies are converting to cloud based computing services because the conversion allows them to save money and have better auditing trails. As a prospective data engineer with ZeRTO Ltd, your interviewer will be looking to hear that you are at least familiar with the concepts of working with cloud based data. Talk in details about the experiences you have while keeping your mind open to working with more in the future if hired with ZeRTO Ltd.

Ryan's Answer
"My current organization has been using Apprenda, a PaaS, that allows us to develop, test and maintain our software projects. I also have experience mining and converting data off of public, community and private cloud networks. If hired here at ZeRTO Ltd, I think I would bring a wealth of cloud based experience to the data engineering team."
10.
Walk me through your experience in enterprise software sales, and complex sales cycles.
Software sales can be complicated, time-consuming, and rarely come with a quick close. The interviewer would like to discuss any experience you have had, selling software products into enterprise accounts, where the sales cycle is even more robust than the typical small to medium-sized businesses.

The typical software sales cycle includes:

- Prospecting and generating leads
- Initiating contact
- Qualifying the lead
- Presenting the product or offer
- Booking a product demonstration
- Overcoming objections
- Closing the deal
- Implementation
- Training

This list is just a simplified breakdown of the steps and could occur throughout weeks, or even months. Discuss the exposure you have had in closing complex software deals.

Ryan's Answer #1
"Although I have never had an official sales title, I am often called into the sales process as the subject matter expert when it comes to data migration and security questions. I know enough to understand the typical questions asked during the sales cycle, and also know that it's important to give case examples for most FAQ's. Decision makers feel much better knowing that their concern has been presented, and corrected, in the past."
Ryan's Answer #2
"My previous company was a startup that ran very lean, financially speaking. For that reason, I was both a front-end developer, product demonstrator, and sales assistant. I would be on the sales calls with the business development lead, offering my expertise for the most technical discussions. From the time we launched our product, to the first sale, was over 12 weeks, so I fully understand that the typical software sales cycle is complex and lengthy, especially when dealing with major corporations and large business."
11.
At ZeRTO Ltd, we rely on a full team effort to deliver top quality products to our customers. Tell me about a time that you worked well as part of a team. Are you comfortable in a similar role here?
While this potential role with ZeRTO Ltd will require your to be an independent worker that can think on your feet, you will also need to work as part of a larger team that is working toward one common goal. Because of this fact, your interviewer will want to hear that you thrive in an environment where you work with team members from other disciplines than you are trained in. In your example, stress to your interviewer that you have excellent communication skills and that you fully understand that every person on a team plays a vital role in the organization's success.

Ryan's Answer #1
"Throughout my career, I've always enjoyed working as part of a larger team on the job and this personal enjoyment started with my love of and participation in team sports like baseball and basketball. Growing up playing sports, I learned that each team member brought a unique skill set that could help us achieve our goals. Through a great coaching staff that knew how to make these individual skills shine, this same philosophy holds true for a team that is looking to design a new software system. I know that my skills as an engineer are just part of the final product and I work very well with designers, architects, analysts and sales to help build the greatest system possible."
Ryan's Answer #2
"I am a people person by nature and my current role has me working very closely with our engineering and design staff on writing technical manuals for our products. While I certainly can handle long days at my computer in solitude, my desire to work hand in hand with others really sets me apart from my peers in this field. I have excellent verbal, listening and written communication skills that, if hired here at ZeRTO Ltd, your entire team would appreciate from my first day on the job."
12.
What SDLC models are you familiar in working with?
As a software engineer, you are very familiar with the software development life cycle. For this question, your interviewer is looking to hear what models you have worked on in the past. While there isn't necessarily a right or wrong answer to this question, try to show your flexibility to working with different SDLC models by bringing up your past experiences. Then, show you have knowledge of different models like the waterfall model or agile model. It is also a good idea to use this question as an opportunity for you to learn more about ZeRTO Ltd by asking your interviewer which model they work off of.

Ryan's Answer #1
"During my training in software engineering and in my early career, the waterfall model was the standard. In this model, each phase of the development process happens in a set order and projects using this model are easily managed. But over time, as the development projects that I have led have become more complicated and intricate, I have implemented the spiral model. This model has allowed the ability of end users to give feedback early on and often during development and helps to build a more customized product to our customers."
Ryan's Answer #2
"In my current position with XYZ Company, my department utilizes the agile model in development life cycle. Since our products are so tailored to the needs of our customers, we get a working product very early on in the process and then I work hand in hand with customers to fine tune the software moving forward. It is a very effective model that has built a great reputation for our software among customers. I also have familiarity working with the iterative model and it has similar advantages to the agile model. If I were hired here at ZeRTO Ltd, can you expand on what models you use here in your software development life cycle?"
13.
Here at ZeRTO Ltd, we ask our test engineers to follow specific QA protocols. What role do you feel QA plays in software development and testing?
As an experience software testing engineer, quality assurance should be ingrained in your brain and your interviewer is looking to get a sense of your personal feelings towards it in your work with this question. In your answer, be sure to highlight QA's importance in reducing errors, maintaining specifications, testing failure parameters and preventing defects from occurring. In the end, make sure that quality is your mantra in the eyes of your interviewer by giving an example or two of how you put QA in the forefront of your work.

Ryan's Answer #1
"As a test engineer, I take great pride in my role of ensuring that systems go out to consumers as error free as possible. In my current role, I take the time to learn all of the system specifications that are laid out by our design engineers and customize my testing to follow those specifications."
Ryan's Answer #2
"In my work throughout my career, quality assurance in my testing was an every minute of every day job on my part. While creating effective testing processes on new software is extremely important in following QA protocols, the recording of defects, issuing of reports and assisting the designers on fixing issues are equally important parts of the process that I'd love to let shine here at ZeRTO Ltd."
14.
In your experience in software testing, would you consider yourself proficient in both testing and debugging processes?
As a reputable provider of software, ZeRTO Ltd relies on their software testing engineers to both test and debug their products when necessary. Make your interviewer aware that you are knowledgeable on both processes by briefly explaining each process as you've worked on them in the past. Then, talk about your openness to working both testing and debugging processes if hired for this position.

Ryan's Answer #1
"Yes, I definitely would consider myself proficient in both testing and debugging software. My current role that I've held for four years since graduating from college has exposed me to both processes. In testing, I use known conditions and predefined methods to test for expected outcomes to find errors within the system. I utilize testing prior to new software rollouts. The debugging process happens to already released software that has had issues and comes with unknown conditions and unpredictable outcomes. In this process, my goal is to find the cause of the error to fix it efficiently and effectively to roll an updated program back out to end users."
Ryan's Answer #2
"While a majority of my career has been focused on software testing, I am very familiar with debugging processes as well. If hired for this position, I would take the time to focus on debugging processes to bring myself up to speed while being able to hit the ground running on testing processes."
15.
If hired here at ZeRTO Ltd, what do you feel would be the biggest hurdle for you to overcome from the start?
The key to answering this question with confidence starts with understanding that you are interviewing with ZeRTO Ltd because your interviewer feels that you are a strong candidate for this position. What your interviewer is focusing on with this question is how they could be of most help to you if hired for the job. So, take the time prior to your interview to think about an aspect of the position that would be the most difficult for you to overcome to be up and running at full speed and then take time to explain how you would plan to overcome that hurdle if hired. This structured answer will tell your interviewer that you have put thought to your potential shortcoming with a plan of action.

Ryan's Answer #1
"As you can see from my resume, I don't have any direct working experience with the financial industry and I would see that as my largest learning opportunity if offered this position. Like I did with my current job in the healthcare industry, I would take the time to learn the basics of the industry that would help me design the most intuitive user interfaces in the products here at ZeRTO Ltd."
Ryan's Answer #2
"Being a team player by nature, I've always considered my first challenge at any new company to be the task of getting to know my colleagues, their work preferences and their work styles. In the same breath, I want them to know who I am and how I best work as part of a team with them. To accomplish this, I would take the initiative to set one on one meetings with individuals that I didn't get to touch base with during my orientation process to get to know them better."
