They didnt have time to talk to you - they only sent pre-recorded videos of challenges. Asked for two design challenges, both took a least a day each. Imagine spending two days of free work for someone and they don't even bother with a face to face. Stopped communication when they didn't want to take it further, had to get the recruiter to squeeze an email out of them with some dud feedback. Judging by the other comments here these were massive red flags that I should have clocked - would not be a good place to work with the poor work ethic and attitude from the CEO.
