Engineers are responsible for designing and building products. In an interview context, expect to be quizzed on your technical skills, and also evaluated for your ability to work as a part of a team to get things built. The specific questions you are asked will depend on what type of engineering position you are looking for. Try a specific engineering discipline, such as software engineer, electrical engineer, or mechanical engineer.
What exact experience with test automation have you had?
Automation starts when UAT becomes stable. Say for instance if on each release more than 50% test are failing you don't automate the application. During this time you can run smoke or black box tests to check if major functionalities are working properly. Once it becomes more stable for instance if 20% tests are failing you can start the automation process. Depending upon the application one can start with developing the frameworks. if it needed to be a data driven framework or a key word dirven framework. The best practice will be to incorporate Hybril Framwork which is combination of both keyword and data driven frameworks. On every release you run your regression tests to check new functionalities and anything broken from the previous releases. Once the application comes closer to complition you can develop a happy path or end to end test to check the functionalities of the application.
