1c Company interview questions

I was reached out to by the recruiter that I am on the shortlist of candidates. She sent me an assignment which consisted of writing a 1000-word paper or doing a video. I decided to do the paper which went to 5 pages. Took a lot of hours doing the paper. I sent the recruiter the finished 5-page paper I was told that they would be going to the next steps. Later the recruiter told me that they would have to reschedule the next round interview after 3 weeks due to the manager planning a big event. I followed up after the 3 weeks and was told by the recruiter that I would have a response in a couple of days. Never received a response.

I was interviewed by the management with no HR specialists present. After the initial formalities were dealt with, one of the managers asked me whether I got my previous job - attention now! - through_the_bed. The previous job in question was at an international AAA company. The 'question', disguised as a joke, sounded so unreal to me that I was left speechless, didn't leave the room and went on with the interview as if nothing wrong has happened. I'll spare you from describing my thoughts and feelings that evening and will only say: people who value human dignity, beware! :D
