The first interview was actually a seminar where the CEO gave a pitch. After that, we were given a Survey Monkey for them to invite some to the group interview the next day. The interview was with a salesperson who was pitching the company to us with no time for us to ask questions. I continued to the last round over the phone and was given an offer. It was 10:00 pm and they needed an answer that night. I asked for the job offer over email and they were offended I didn't say yes right away. I politely declined and was ghosted. The last interview confirmed red flags and left a bad impression. It was handled unprofessionally.
