Apprentice Engineer Interview Questions

5,558 apprentice engineer interview questions shared by candidates

One of the key questions they asked me in the Morgan Stanley technical interview was about the concepts of OOP—specifically polymorphism, inheritance, and how method overloading and overriding work internally. The interviewer wanted to check whether I understood not just the definitions but also the rules behind them, such as how access modifiers, return types, and exceptions behave during overriding. I explained that overloading is resolved at compile time based on parameters, while overriding is resolved at runtime using dynamic dispatch. I also mentioned that visibility can only be increased while overriding, and child classes can throw only narrower exceptions than their parent. This question helped them assess my clarity in Java fundamentals and my ability to explain concepts precisely and confidently.

most difficult part was the online assessment period. i had to wait a week to see if i had made it through to the next stage. and the test were unexpectedly easy. i did not finish some and did not answer all of them correctly, but i still made it through. the last online test which is the diagrammatic test, was difficult to me as the shapes confused me somewhat, but i still managed to pass surprisingly.
