I had applied for a Tech Recruiter role at Facebook London 9 months before being contacted by one of their Recruiter. We scheduled a call end of August 2019, the Recruiter didn't call - apparently a technical issue that led the interview to be booked in the wrong day on her end. We finally had a telephone interview in Sept and agreed to reconnect in a few months. Few months later, I reach out, she offers to schedule another call (yay). She cancelled the call the day of the interview (said she was running an event that will run over) and offered to speak on the following Monday. Never heard back. I followed-up by email, she never responded - it has been 1.5 months now. As a Recruiter myself, I'm unimpressed by the quality of the work of their Talent Acquisition folks. Interest lost.
