Sundae interview questions

The hiring manager found me and reached out to me via Linkedin. Once I agreed to apply, I was scheduled to interview with 4 senior executives/managers. The offer came shortly after the completion of the last interview. I started to work for the company 2 weeks later.

I was interviewed 3 times. Was promised I’d be sent an offer letter within a week. Two weeks later, I reached out and was told there was a hiccup with HR and I’d hear back within another two weeks. Never heard from the company/hiring team again
