This was the most unprofessional interview experience ever. No questions were asked based on my skill set in my resume. They gave me a problem to solve (design and verify) which I was fine with, but in the meanwhile the interviewers were discussing some random stuff not related to the interview which was distracting. They were least bit interested in what i did and it was extremely unprofessional. The worst is they never got back me to with the interview result.

Its a phone call interview for 45min. It started with questions on projects in my resume. It continued with technical questions on verification methods. The third step of the phone call interview is the interviewer told about his team and company.
