I scheduled a phone interview with Tracer recruiter and they didn't call me, then I emailed the recruiter to get the reason why nobody called me. They emailed me back saying sorry and reschedule the interview. We reschedule the interview and nobody called me again, I emailed them, but nobody even followed me back. I don't know maybe something happened, but at least they should notify before or don't reschedule the interview if they're not going to call.
