I think interviews are a very subjective thing. Maybe this person was having a bad day or maybe it was just a mismatch of personalities? My son felt like his went well but he could also say a lot of things you said. His interviewer also checked her phone a number of times because she had something important going on for work but did warn my son and apologize. He also brought a project on his tablet but they had enough of a back and forth conversation that they never got to it though he did feel like she wasn’t that into it or she would have wanted to see it. His interviewer also implied a number of times that it would be difficult to get in which is true for any candidate. She was cheery and positive but that is the reality of the situation. Some interviewers never have any candidates admitted and they feel bad interviewing wonderful candidates that they know would be successful but the odds are just very low. I’m glad you feel like your issue was resolved but I don’t think your experience was that far off the norm when people just don’t click.
