Collabera Technical Recruiter interview questions

I appeared on campus drive, the process took two days. Group Discussion was the Last round which lasts till mid night and next day selected students were told that they will receive phone call from the company for the final interview. I was selected but didn't got call and on asking I was told that in next month I'll receive the call but I didn't, really disappointed.

3 people, in the office and went up to meet everyone, talked to them in the meeting room, very out of it and awkward, not very friendly group of people
