I was called for an onsite interview in NYC. I had a three-hour interview session, and I was interviewed by two developers.

The first interviewer asked mostly design questions, about different SDLC stages, and performance testing.

The second interviewer was rude and had a know-it-all attitude, even though I answered many of his questions correctly.

The interview was not planned properly; when I arrived, they hadn't registered me, so I had to wait at the front desk for a long time.

I was asked to design a database based on the requirements given by the interviewer and had to write some queries.

I was also asked an object-oriented design problem.

Details about Performance Testing.

Explain dynamic and divide-and-conquer programming.

Implement Fibonacci using iterative, recursive, and dynamic programming.

Explain merge sort and how it uses divide-and-conquer programming.

Implement a circular linked list based on a given problem.

Discuss the differences between linked lists and array lists.

Discuss the differences between C++, Java, and Python. (I did not revise C++ much, so I couldn't answer virtual functions in detail).

Explain the difference between Future and Callable. Explain Executor Services.
