One of their new consultants encouraged me to come in for an interview (even though they did not actually have any role for me), I waited in a room for 15 minutes alongside another guy who was double booked in for the same time as me. Had to wait another 15 minutes for her boss to interview me, 30 minutes of meaningless recruiter waffle chat later about the kind of roles they sometimes get in, and I've wasted an hour. I go to leave, see the recruiter who was supposed to interview me and she is laughing and chatting with the receptionist and pretends not to see me and doesn't bother apologising. 0 clue 0 professionalism.
