Infosys Team Leader interview questions

It was one to one interview with two rounds.

I went 30 mins before my scheduled interview but had to wait 4 hours before I was finally called. Even though they called me to Infosys office for face-to-face interview they setup a telephone interview in the office. Then they had a group panel interview. Later I had a 1:1 with HR and discussed about the offer. The offer was not too great but I asked for sometime before I could respond. I tried reaching them after 2 days and tried several times after that through email & phone. Not a single response !!! Even the staffing agency which arranged the interview couldn't get any response! Very unprofessional HR department I guess!
