GLG Recruiting Sourcer interview questions

I applied for an entry level position at the company right after graduating college. I have a handful of friends who work there so I was very excited when I was offered a phone interview. However, I felt that my interviewer was very condescending and short with me. Overall, the interview left me with a bad taste in my mouth about the company. I was not at all surprised to find out I did not make it to the next round of interviews as I was very taken aback by the interviewers attitude and did not perform my best.
