2. What SDLC models are you familiar in working with?
How to Answer
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 Oracle by asking your interviewer which model they work off of.
Written by Ryan Brunner on February 24th, 2020
1st Answer Example
"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."
Written by Ryan Brunner on February 24th, 2020
2nd Answer Example
"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 Oracle, can you expand on what models you use here in your software development life cycle?"
3. If hired here at Oracle and tasked with helping design a UI for a new mobile app, what important factors would you consider in that design?

6. If you can, please provide your thoughts on the function of managed object context in developing iOS apps and software.
How to Answer
While the core data framework and the managed object context may seem pretty easy to comprehend and simple from a first look, a deeper look into managed object context shows that it can be misused to the point where obscure bugs can enter the system. Give your interviewer your own personal insight into the purpose of managed object context and how it works behind the scenes to help an app properly run.
Written by Ryan Brunner on February 24th, 2020
1st Answer Example
"In my current work, I work with both main queue and private queue manged object contexts. It is important that I avoid non user related data processing on the main queue of an app that I am developing. In times where this has happened in the past, the user interface becomes unresponsive and crashes. As well, I work to avoid instances passing between the main and private queues to avoid corruption of data within the app."
Written by Ryan Brunner on February 24th, 2020
2nd Answer Example
"Knowing that a managed object context's job is to manage a number of records within an app, my job is to successfully manage each object within the app and assign it to a correlating context within the app. I have to consider the persistent store coordinator and code the app to fetch requests from the correct one."
7. If hired here at Oracle, what do you feel would be the biggest hurdle for you to overcome from the start?

2nd Answer Example
"If you were to offer this position to me, you'd quickly find that my positive attitude is an inspiration to those that I work closely with. In my current job, we work under the constant stress of tight deadlines and my positivity can be infectious to help others maintain their focus when negativity can easily take over in most situations. I would say that my other strong suit as a natural leader is my ability to be fluid on a day to day basis. Sometimes our world can be monotonous and when change comes, most resist that change. For me, change is a chance to break the current mold and grow as an employee."
12. Do you consider yourself stronger in C++, C#, Java, or Python?
How to Answer
Before your interview, do some research to understand what tech stack Oracle uses so you can best prepare and highlight your expertise.

Written by Ryan Brunner on February 24th, 2020
1st Answer Example
"In my current work, I use a very methodical fashion in cleaning data for finished systems. My first step is to remove duplicate and irrelevant observations within the data. Then I scan the data to remove extra spaces, convert numbers stored as text into numbers and remove duplicate data. These steps help ensure clean and accurate data and I never overlook them. If hired for this position, what methods does the current data analyst team her at Oracle utilize?"
Written by Ryan Brunner on February 24th, 2020

By doing this, they feel like they are an important part of the process and it reflects well on me and my organization."
Written by Ryan Brunner on February 24th, 2020
2nd Answer Example
"In my current role, I'd definitely say that a majority of the maintenance work that I do is adaptive maintenance. Working in banking software that is used around the globe, I help perform system maintenance for changes in currency on a pretty regular basis. This work requires research and talking with end users to help adapt the programs for their use. If hired here at Oracle, I also have experience performing perfective, preventative and corrective maintenance on software as well."
18. Do you have any unique skills or past work experiences that we can't see on your resume that would benefit the team here at Oracle?
How to Answer

19. In designing Android software, what is your experience using parcelable versus serializable within an app?
How to Answer
Because parcelable is optimized for Android to be faster and more customizable, your interviewer will be looking to hear that you are willing to put in the extra work to utilize the parcelable method to achieve better performance within the software that you design. Give your interviewer your thoughts on the differences between the two methods of passing object references to activities within an app that you design and make sure that they understand that you are ready to perform the work to utilize the parcelable method when necessary.
Written by Ryan Brunner on February 24th, 2020
1st Answer Example
"Having written code for Android apps for many years now, I am very familiar with both serializable and parcelable methods. In my first hand experience, parcelable provides a much faster and better user experience so I will always strive to take the time to write custom code for marhsaling and unmarshaling to create less garbage objects within an app."
Written by Ryan Brunner on February 24th, 2020
2nd Answer Example
"Due to it being a standard Java interface and its ease of implementation, serializable interface is pretty commonly used. But, because it uses reflection, many temporary objects are created within Android apps and this creates a very poor user experience. When the parcelable interface was introduced for Android systems, I have extensively focused on its use and finished products have benefited greatly."
20. When do you consider a project to be finished?
How to Answer
When answering this question, be sure to understand what the employer is truly asking. They are looking to see where you think the project ends, whether that is when it's completed and all testing is done, or whether you think projects are ongoing and require constant work. It can be a trick question as many companies believe a project is never truly finished. Be sure to give an explanation with your answer to back up your belief.
Written by Marissa Letendre on February 24th, 2020
1st Answer Example
"In my mind, a project is never truly finished. Once it's rolled out, upgrades will have to be performed, quality checks will have to be completed, and the product will inevitably change based on customer needs, new technologies, and trends in the market. We have to take that all into consideration when working on a project and while maintaining the product that was completed as a result of the project."
Written by Marissa Letendre on February 24th, 2020
2nd Answer Example
"I should disclose to you that I have a mark on my criminal record. I have a DUI from 1998. Since then I have maintained a clean record and I am willing to comply with any form of background check that you require."
21. How would you handle a situation where a colleague was being very difficult to work with?
How to Answer
In the team based atmosphere at Oracle, departments with different skills and backgrounds can often see things from different points of view and these situations can cause some internal conflict between coworkers. With this question, your interviewer is looking to hear how you handle situations where you are working with someone that can be seen as difficult. To give them the sense that you are able to work through conflict in a professional and sensible manner, try to talk through how you handled a conflict at work previously in the past and highlight the interpersonal skills that you used to help make it a positive situation.
Written by Ryan Brunner on February 24th, 2020
1st Answer Example
"In all honesty, any great work atmosphere that I've been a part of in the past has involved conflict between colleagues. In situations I have witnessed, conflict has stemmed from very open-minded people giving their two cents in particular situations and two people not seeing eye to eye. This happened recently to me in the planning phases of a new project. On of our UX Designers and I had a disagreement on the final layout of a new software roll out we were planning. It worked best for both of us to talk about our ideas and list the pro's and con's for our ideas. I kept an open mind to learn from her point of view and she did the same to me on my end. This led us to come up with a great compromise in the end."
Written by Ryan Brunner on February 24th, 2020
2nd Answer Example
"Last year, we had a new engineer join our team that was hired on from his internship with us. From his first day, he made it very evident that he would only handle certain tasks within our team and only work on certain projects. As his mentor to help get him up and running, I sat him down and discussed the expectations of each of our engineers as part of our larger team. I explained to him that our approach was not to pigeonhole ourselves into smaller tasks, but rather be well rounded engineers that could handle any project and be able to cover for each other if needed. He really appreciated this approach when I explained the benefits for his long term career goals with this approach. This example shows my approach to being very direct with people that I have a conflict with in the workplace and doing so in a very professional and educational manner."
22. What skills do you use to cope with the day to day stress and pressure on the job?

As you answer the question, try to turn potential perceived stress into a positive by highlighting your personal skills that enable you to perform well in those situations. If possible, try to use specific examples in your answer.
Written by Ryan Brunner on February 24th, 2020
1st Answer Example
"Where many others get overtaken by stress to the point that they can't function in this field, high pressure situations sharpen my focus and that helps me work through them with ease. Last year, I was assigned a high priority, short notice project for a high profile customer. My manager gave it to me because of my proven success in those situations. From the start, I created a timeline for completion and mapped out a plan to make it happen. While staying in communication with my leaders and the client, I was able to create a great system update in just a few short weeks."
Written by Ryan Brunner on February 24th, 2020
2nd Answer Example
"I am confident in high stress work situations because of my ability to adapt, communicate and be organized in my work. These skills came in very useful a few weeks ago when our support staff were experiencing an extremely high volume of help desk calls. My adaptability helped me go with the flow and handle items on at a time. My communication skills enabled me to quickly and efficiently call on needed support. My organization skills helped me be prepared for anything on that day and enabled me to work through tickets in a quick and efficient manner."
23. Do you have experience writing a custom exception in Java?
How to Answer

25. In SQL, how do you explain the differences between clustered and non-clustered indexes? Can you name a time that you used each?
How to Answer
Oracle uses indexes to improve query performances within their software and for this question, your interviewer is looking to hear that you have a basic understanding of both clustered and non-clustered indexes. Explain the differences between the two types of indexes and be sure you can either speak to relevant times that you've used each or when would be the appropriate application to use each.
Written by Ryan Brunner on February 24th, 2020
1st Answer Example
"In the simplest of terms, a clustered index order records in a table the way that they are physically stored. There can only be one clustered index per table. Non-clustered indexes do not store data to match the physical order that it is stored. Rather, it can hold up to 249 indexes per table. Both types come with their own benefits over the other. In my experience, clustered indexes are suited best for programs that use primary key as an identity integer column. On the other hand, non-clustered make the most sense for programs that need JOIN and WHERE clauses within them."

2nd Answer Example
"In my experience, clustered indexes are faster to read but very slow when it comes to update data within. Non-clustered indexes are just the opposite in that they are slower to read but much fast to insert new data into them. In my current role, I mostly use clustered indexes when large numbers of rows need to be retreived and when insert operations are important. Most other times, I will use non-clustered as the standard."
26. In your current work, what are the important steps you take in the data validation process?
How to Answer
Depending on your training and your past roles prior to interviewing at Oracle, you may be familiar with one or two of the many trains of though regarding the steps of a data validation. Whatever formal process you are familiar with, be sure to check the boxes of discussing data screening and data verification as part of your process. Your interviewer will be looking to hear that you check those boxes as they are imperative in the software field.
Written by Ryan Brunner on February 24th, 2020
1st Answer Example
"As I embark on a data validation process in my current role, my first step is to roadmap a detailed plan to keep on task. I utilize benchmarks and the expectations of key stakeholders as my guide. Once underway, I validate the database and the data formatting to ensure that data is properly screened for its overall health. Then, by finishing with sampling, tests are performed to hopefully show that the data is useful within the system."
Written by Ryan Brunner on February 24th, 2020
2nd Answer Example
"The most important steps in a data validation process are determining the data to sample, scouring the existing database and validating the final data format. My first step is to use my best judgment to determine if I will validate a sample or the entire data set. This determination is based on overall size of the set and the timeframe that I have to work on the project. Then, I take the time to screen data in the existing database to calculate the number of unique ID's and records to come into the system. Last, I have to verify that the source data matches the schema within the targe"
27. Do you have experience working with different CASE tools? If so, what do you have experience with?
How to Answer
The world of software engineering has greatly benefited from advancements in computer aided software engineering tools. Because Oracle 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.

"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."
Written by Ryan Brunner on February 24th, 2020
2nd Answer Example
"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 Oracle."
