Responded within 24 hours after I submitted the application. The job requirements were really interesting.

I went through two phone interviews. These involved basic knowledge questions, not hard coding problems.

I went on-site for interviews about two weeks after the last phone interview.

Everything felt good. The company is clearly a more than awesome place to work, though I myself am to blame for coding some really poorly in one of the coding interviews. That might be the major reason I was rejected.

There is only one unpleasant experience: the system design interview. The interviewer kept prying into the system architecture I designed during my last summer internship at a small startup. He asked for every detail and was clearly impatient and displeased with the simple design I presented. This made me uncomfortable, as his questions were based on past events that I couldn't change. Clearly, my design was also based on practical needs and conventions already established at that company.

Wouldn't it be more appropriate for questions to be framed like, "What's your opinion on X situation? What would be your ideal design if faced with X?" Instead, I received responses like, "Oh, so you guys made it this simple? Why?" with displeased expressions.

I felt it was unfair because he was evaluating the company I interned in, not me. I just hope these kinds of interview questions can be better designed. Nobody likes being put in a situation where they either have to lie about what they did or admit to a naive design, which was actually very reasonable under those specific practical circumstances.
