I was contacted by a recruiter after having previously interviewed for a different position that was ultimately awarded to an internal candidate. They were adding additional headcount to the census and reached out to see if I was still interested. We had a quick catch up call and then they set me up with the hiring manager the next day. I never heard from them again, despite several follow ups to both contacts. The experience was, in my opinion, a horrifically disrespectful and unprofessional waste of my time.
