My last job was a complete nightmare and i saw the red flags during the interview but choose to ignore them because the job was good experience. The manager seemed a bit awkward, didn't have a copy of my resume, took a long time to ask the first questions, etc. When I asked him, "What's the company culture like?" he immediately lashed out at me with "What was your company culture like?" talking about my previous jobs. I was a bit taken back by his response, he claimed he needed an example. He also stated he worked 18 hours days and has taken a vacation in ages. He also lashed back at me a couple more times during the interview, for example I asked him "Does he still program?" since he mentioned he had a CS degree and he responded with "I do whatever I need to do." again it took me back. I left the interview praying he wouldn't make me an offer and a week later HR called to make an offer, I couldn't believe it but I decided to accept because I was a bit desperate and needed the experience. The HR manager was a complete psychopath. She would lie to my face, refused to tell me information about the job, and overall just gave me a very bad vibe. I ended up quitting a month later in a blaze of glory.

I've also had an interview with an MSP where the owner was 20 min late to the phone interview, company misspelled computer with compuetr on job description, owner refused to answer some of my questions, etc. I have many more red flags that I saw during interviews but those were just a few.
So what red flags did you guys saw during interviews? What do you guys think? Thanks in advance.
