I was contacted by hiring manager about a month after I applied to have a first-round interview. The interview was very short, I was only asked a handful of questions, which I found strange. I honestly thought the interview went extremely well other than that. I was comfortable and had well-prepared answers, and the hiring manager seemed to receive them well. I was very shocked to find the rejection email in my inbox after the holidays. I guess you can do everything right and still get rejected.
