Reformation Technical Designer interview questions

One -on- one interview with hiring manager and an IQ test. Hiring manager had a bit of a confrontational attitude and the IQ test was a mixture of strange questions and maybe useful information to make a judgement of skills needed for the job.

Applied online on a Friday, got an email after a few days to schedule phone interview. Had a phone interview next week, in person interview a few days later with three different people at the company, and job offer a few days after the interview. Unfortunately after offering me the job and then asking me several times when I could start, could I start next week, actually what about a week later, etc, then ghosting me for another week, I asked them to please confirm with an official written offer. I was shortly informed they decided not to hire for this job after all... Very unprofessional, frustrating. I wasted two weeks I could have been looking for another job.
