I reached out to them on the internet. Their recruiter had to reschedule the first phone screen and it was a pretty normal call except that he asked illegal questions like "are you married" or "do you have family". Then I was scheduled a call with the CTO. The CTO failed to call and ultimately called like an hour after the scheduled time and nobody told me until I reached out to the recruiter so I just wasted an hour waiting. The call with CTO was pretty basic and he was more interested talking about himself than to get to know me. I had to reach out to them 2 weeks later to be told they would pass. Very unprofessional. Too bad, they have an interesting product.
