HR called and scheduled an interview even though I told them that I was a misfit for the requirement.

There were three rounds of interview:

• The technical interviewer asked me my salary, which I didn't like.
• He gave some performance problems to solve.
• This was followed by another round where he asked me to find the complexity of some programs.
• Finally, there was another round where they asked a couple of programming questions.

At the end, they said they would get back to me (which obviously means they didn't like me). I also didn't like them due to the interviewers' attitude; they seemed very disinterested in the whole process.
