1.
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 Schlumberger Information Solutions 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 Schlumberger Information Solutions."
2.
Do you have experience utilizing Bayesian networks in designing artificial intelligence?
Because of their ability to provide a graphical model for relationships among a set of variables, Schlumberger Information Solutions is a firm believer that Bayesian networks are a critical part of their artificial intelligence design. To fortify your knowledge of the networks, give a high level overview of your understanding of them and also talk about any experience you have in utilizing them. Make sure your interviewer walks away from your conversation knowing that you are able to utilize Bayesian networks in your future work with Schlumberger Information Solutions.

Ryan's Answer
"I do have very direct experience in creating Bayesian networks and I've done so in the healthcare industry over the past couple of years. One that we designed looked at all of the potential symptoms and effects of heart disease and built this all into a very complicated Bayesian network. With this given, we were able to create an AI program for a health insurer that could program in known information from their insured individuals to gauge their probability for heart disease."
3.
Tell me about a time your manager changed the scope of the project in the middle of it. How did you deal with it?
With this question, your prospective employer is looking to see how you handle change, especially change that can be frustrating and disrupting to your work. In your answer, be sure to explain what happened, as briefly as possible, and how you handled that change to get back up-to-speed and on-track with your project.

Ryan's Answer #1
"We were working on a software upgrade project which was supposed to take 12 weeks; however, 4 weeks in, my manager approached us and requested different modifications, even though the modifications were almost 75% complete. I understand that changes can happen and it was my job to get back on track and get going on it. I immediately took action and worked with my team and manager to come up with a plan moving forward, as that disrupted our schedule. We were able to all pick up extra and through that, we still hit our initial deadline."
Ryan's Answer #2
"I can assure you that, if hired, I would put the customers of Schlumberger Information Solutions first. When working in the financial services world, your customers can determine your success. I have a very high referrals rate which tells me that my customers are happy."
4.
Schlumberger Information Solutions embraces an Agile environment. Explain your experience in Agile methodologies and why you think it is important.
The interviewer would like to understand the depth of your knowledge in Agile. The interviewer would also like to know if you work well with team collaboration, are responsive to stakeholder needs, and can work well with team defined milestones. Give a specific example of your experience.

Ryan's Answer #1
"The majority of my experience has been in an Agile environment. For ten years I have been personally responsible for leading agile teams, and I have helped define team goals and milestones. This approach is important to me as I see how Agile methodology helps employees deliver better products in less time. In my current role, team productivity increased by 34% once we introduced an Agile environment, and our on-time project rate skyrocketed another 18%."
Ryan's Answer #2
"I especially want to work for Schlumberger Information Solutions because I have friends who have worked here before with really positive feedback on their experiences. I am looking for a positive work environment where I can stay for a long time to come."
5.
As a machine learning engineer, how do you avoid the curse of dimensionality in your designs?
To effectively answer this question, it is important to first understand what dimensionality means in reference to machine learning and how it can curse a project. As the number of features increases in comparison to the number of observations within a data set, some algorithms struggle in pulling correct data. Your job on this question is to talk about ways that you can avoid the curse in your designs. Some possible things that you may mention and describe are feature selection, correlation thresholds and variance thresholds.

Ryan's Answer #1
"A common example that I use with people to explain complications in dimensionality is dropping a pin on a 10 foot straight line. This would be relatively simple to find. Next, if you dropped the pin in a 10 foot by 10 foot square, the task of finding the pin becomes more difficult. Adding a third dimension to make a 10 foot cubed area makes it all the more difficult to find the pin if placed within it. In bringing this back to machine learning, my job is to somehow make the three dimensional field that the machine will pull from easier to pull from. Last year, I was part of a team that developed a system for pulling public health data. We were able to set many variance thresholds that removed values that didn't change much from observation to observation. After careful testing, the system was able to pull information quickly and accurately based on these thresholds."
Ryan's Answer #2
"As you can see from my resume, I've spent the last six years working in the electronics industry. Most of my machine learning work has focused audio data. To avoid the curse of dimensionality within the systems I've designed, autoencoders have been tremendous in pulling information. While a great amount of time and effort was needed to effectively train the systems, the work was well worth it in the end."
6.
The next cloud engineer that we hire here at Schlumberger Information Solutions 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."
7.
We are looking for innovators to join us here at Schlumberger Information Solutions. Where have you brought innovation in automation to a process in your career?
Innovation in software has occurred in many phases over the last 20 years and Schlumberger Information Solutions is always striving to be on the forefront of innovation in their field. For this question, think back on your automation experience and talk about a concept that you helped create that you felt was innovative. Really sell your interviewer on your ability to think outside of the box with this question by hammering home the idea that you can help bring new innovations to the team at Schlumberger Information Solutions.

Ryan's Answer #1
"To be very honest with you, I was really drawn to the automation side of engineering because of the constant need to be flexible and continuing me education to stay ahead of new trends. Last year, I helped develop a codeless test automation for my company that brought together our software engineers and end users to test in environments in a fast and efficient manner. The codeless testing was a first for my organization and really helped free up time for our software engineers to come up with solutions rather than spend time testing."
Ryan's Answer #2
"About four years ago, I was on a team that developed an AI bot that could test scripts and provide analysis on extremely large amounts of data in a short period of time. Our work focused on the algorighms that the AI would utilize in its testing work. From the start, the AI process was extremely accurate and efficient. Now, as things have changed over time, modifications to the AI system all center around changes to the algorithms. Based on our success, we presented our AI system at a national conference last year and it received a lot of great accolades."
8.
Give an example of a time that you used a universal design practice in your work as a UI or UX designer. Why was it important to do this?
In the technology, software and mobile app fields today, accessibility is a huge topic. As a designer with Schlumberger Information Solutions, you will be expected to help create products that are as accessible as possible to as many end users as possible. In this two part question, talk about why you feel that universal design is important in the work that you will be doing with Schlumberger Information Solutions and then really sell your ability to do this by giving an example of a time you used a universal design in your previous work.

Ryan's Answer #1
"From a very high level, the business success of a program really relies on being universally designed. If we pigeon hole ourselves, a product will only reach a very limited group of end users. But taking that a step further, universal design is the morally right thing to do to help reach people that may not have access to the average program design. Last year, I was part of a project that utilized a voice user interface for users that were deaf or hard of hearing. This simple yet effective design was a huge win for our current customers and in helping drive new business with our groundbreaking software."
Ryan's Answer #2
"Early in my career, the best piece of advice that I receive was from an experience designer and she said that when UX doesn't consider all potential users, we are no longer working on the user experience. We live in a very diverse world and the programs that I've designed for in the past have certainly had the goal to reach a wide audience. With your financial products here at Schlumberger Information Solutions, this same philosophy applies. Last year, based on some feedback from current customers, we switched our design to include a strong color contract to make the system much more user friendly to color blind users. This was both a simple and very effective change to enhance the look of the program."
9.
If hired for this position here at Schlumberger Information Solutions, would you be comfortable handling overall project manager responsibilities for new software development?
As a skilled software engineer, you have all of the necessary tools in your bag to be a successful engineer at Schlumberger Information Solutions. This question is allowing your interviewer to get a better sense of your project management skills and people skills if you were to join the team at Schlumberger Information Solutions. In your answer, talk about your ability to estimate the time and cost of a project, the staffing needed and the overall scope of planning for a particular project. If you have direct experience in being the lead on a large development project, be sure to discuss that experience with your interviewer.

Ryan's Answer #1
"Looking to join the team here at Schlumberger Information Solutions directly out of college, I feel very confident in my abilities to manage the entire scope of a new development project. I have leadership experience as my campus' president of the software engineering club. In that role, I developed skills that would help me utilize staff and resources in the best way possible. During my internship, I was exposed to the planning stages of new projects and I have a very good feel of estimating the budget and length of time needed to have a fully functional system."
Ryan's Answer #2

11.
Software technology continually changes. How do you stay current on new technologies and sharpen your skills?
As technology needs rapidly change for each company, the interviewer would like to know how you adapt to new technologies. This question also gives the interviewer an opportunity to hear more about your learning style and how you take the initiative to learn new things. Interviewers like to hear about specific courses or training, but try to keep them as recent and relevant as possible.

Ryan's Answer #1
"I enjoy learning about new technologies in the software space both personally and professionally. I like to read software and data related articles, and I recently completed an 'Introduction to Python for Data Science' course to help build my skills, even though my current employer didn't require it."
Ryan's Answer #2
"I define success by what we achieve as a team. The project, as a whole, needs to deliver on expectations before I consider the job a success."
12.
Do you consider yourself stronger in C++, C#, Java, or Python?
Before your interview, do some research to understand what tech stack Schlumberger Information Solutions 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 Schlumberger Information Solutions."
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."
13.
What software analysis and design tools do you have familiarity working with?
As a software engineer for Schlumberger Information Solutions, your interviewer wants to hear that you have experience in utilizing tools that you make you more proficient in your work. Dig back on your past experiences and talk openly about your experiences with the different analysis and design tools that are available to help you be better in the work that you do. In the end, make sure that your interviewer understands that you are proficient in the use of these tools and open to learning and using new tools as well.

Ryan's Answer #1
"As my career and experience in software engineering has grown over the years, I've come to really appreciate and utilize these tools that are available. A great example of this would be my recent education and use of Structured English for designing insurance claim software for a large auto insurer. The simplicity of the structured decisions in the program were a perfect example of a program that could utilize the tool and the end product ended up very functional for our customer."
Ryan's Answer #2
"I have great working knowledge in creating and reading data flow diagrams. To help with both our own sales staff and with customers, DFD's have been super helpful and I consider myself very proficient in creating them. I've also recently been introduced to decision tables to aid in product testing. I was working on a new system that involved some very complicated business rules and the decision table helped outline everything perfectly for our testing."
14.
Here at Schlumberger Information Solutions, 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 Schlumberger Information Solutions."
15.
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 Schlumberger Information Solutions 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 Schlumberger Information Solutions, can you expand on what models you use here in your software development life cycle?"
