The first two interview questions were about design, and the last one was a coding question about graphs.

It was quite frustrating for the design questions, as the interviewer did not provide a reason for needing to design the class.

It was even more frustrating in the third interview, where the interviewer did not speak very good English, making it hard to understand the problem.

I would hope they could write down the problem, and that there would be more time to focus on the problem itself.

Design a rectangle with follow-up questions for overlapped areas.
