Avaya Senior Software Engineer interview questions

A friend referred me. I got a call from the recruiter for basic screening and later she went on to schedule a telephonic interview. I was interviewed by two technical team members. Weeks later I go another call stating I have cleared the round one and was asked to come in for the second round. A couple of days later I had the second round, things went really well, atleast I would like to think that. There was not response for over a month. I tried mailing and calling the recruiter, no response. Then one day I got a call from a senior recruiter, asking if I was still available. I responded positively and he scheduled a HR round of interview and finally the offer.

Don't waste your time interviewing here.. They took 3 long Technical Rounds covering Java and Problem Solving plus 1 director round for fitment test ..After few days, when I didn't hear from recruiter, I tried contacting through email but they didn't reply back, later when I called, I got to know that they are not considering my profile.. Recruiter was very unprofessional..
