Had a positive phone screen, invited for an interview downtown in March 2019. Met with 5 people, one after the other, who all asked me the same questions (clearly no coordination); I was getting bored and irritated by the end as a result. Everyone seemed to have an attitude and clearly didn't want me there. First IT guy was friendly, the second one was consistently surprised that I didn't have skills that I didn't list on my resume. I correctly described the difference between UDP and TCP, but he reacted negatively. The executive had nothing to really ask me and was a little combative when I answered questions about procedures at my current job. The talent acquisition guy had a sour look on his face and asked why it was "taking so long" to complete my Master's. Had to point out that I am a part-time student (which goes without saying), I've only been enrolled for a short time, and that I was nearly finished. He couldn't be bothered to see me out. Got a rejection email without explanation.
