BK Behavior Ventures interview questions

Disappointing. They contacted me by email to schedule an interview via a link, I scheduled it, and they never called me. They were supposed to contact me, as it was a call to my personal phone (which is unprofessional), but they ignored me and no one called. After half an hour had passed and I still hadn't received a call, I contacted them again by email and they didn't respond. Before the interview, I already had the feeling that they weren't trustworthy because of the little information I found about them. Run away from here, it looks like a scam, and if it's not, it's the most unprofessional company I've ever come across.
