Standard phone screen. The call went fine, but the recruiter totally disappeared from then on out. I followed up shortly after to thank them for their time. Then several times after to ask about updates. Three months later, no response. No follow up. Nothing. Very unprofessional. Don't bother responding to their recruiters if they reach out, they just want to waste your time.

Totally a mess. Attended a recruiter screen call and received the invitation the same day. But the next round with the hiring manager was scheduled for two weeks later (although I tried to schedule it ASAP)! The hiring manager delayed the interview by one day without any clear reason, but the recruiter insisted that there were 2 headcounts available. Even the rejection was delayed to the following week.
