I had a referral, so I was directly scheduled a 45-minute virtual interview with the hiring manager. They were 15 minutes late, and clearly did not read my resume at all. I have 20+ years of experience and the only question that they asked me about my skills and experience was "tell me one thing you did at ." That's it. They didn't ask anything about my past projects, teams, skills, accomplishments, just tell me one thing you did in 20 years. After that was a coding question. I solved it in one line, but they said that I couldn't do it 'that' way, so I spent the next 20 minutes figuring out how they wanted me to solve it. There was no discussion, just me thinking and typing out code while they clearly did emails or whatever on their other monitor. Not engaging whatsoever. At exactly the 45-minute mark, they said "our time is up, sorry but you don't have any time to ask questions about the job or company, bye" and abruptly logged out. Super unprofessional in my opinion and a colossal waste of time. Generic rejection email within the week.
