Engine Staffing Services interview questions

A 3rd party recruiter initially reached out to me on LinkedIn and set me up with an interview with the CTO. He went over what the product does and some example use cases. After the interview, I reached out to my contact to see what was going on. She had no luck in getting a hold of the CTO after that point. Clearly not a very professional company. Don't bother wasting your time interviewing with this company because you'll just get ghosted if they aren't interested.
