Axiom Software Laboratories Software Developer interview questions

The interview process is ridiculous. Got a call from the HR asking me to come to office the very next day. 3 rounds of interview. one with HR , one with 2 developers who are insane. They asked me questions in probability and were chatting and laughing the whole time when I was solving. Most irritating and useless interview that I attended ever. The last one was with manager who asked some basic questions and was not convinced with any answer that I gave. Totally it is a waste of time where I travelled and wasted the whole day for this interview.
