I went through one of the most unprofessional interview experiences of my life. Red flags were evident from the start. They contacted me out of the blue requesting to schedule a call that same day. They sent an invitation and then changed the time without consulting me, all on the same day. The interview itself was fine. The questions and conversation were normal. The interviewer said she wanted to move me to the next stage and that she would reach back out. I agreed and waited. Days turned into weeks and I never heard anything. When I eventually followed up, instead of a direct response I received automated emails promising I would hear back soon. This repeated twice over the course of a couple of weeks. It is baffling why this HR representative feels they can avoid direct communication. A minimum level of follow-up effort is expected especially when there is mention of a next step with a hiring manager.
