I got a call from recruiter on SUNDAY morning at 8:30 , that an interviewer wants to proceed for technical phone interview on SUNDAY at 12:00.I sent the confirmation. I was waiting for the call at 12:00. Instead I got a call at 12:25 p.m.The interviewer told me he has 10 minutes to talk to me. We talked for 7-8 minutes. It was very unpleasant experience.
