      How to Answer

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?"
