Wellhub Business Development interview questions

I went through 2 phone screening calls with GymPass, each of which took 30 minutes or fewer. After that, I was brought into their New York office (a WeWork space) and interviewed 1:1 with two of their Northeast Region heads of Business Development. The two gentlemen were nice enough, though one of them focused a lot on numbers and math in the interview - including mental percentage math which I did fine, but didn't really understand why that was being thrown at me. I followed up with their recruitment coordinator since I had other offers on the table and I was informed I would hear early the following week. I was smart in accepting a different offer because 3 weeks later and still haven't heard back from them. I didn't know ghosting was a new way for companies to operate.

Started with a phone screen, then went to an in-person interview then a final phone call with someone else in the company from another department. I had a great rapport with everyone I spoke to/met with. After the last phone call, I was given a verbal offer, but nothing official because they were "waiting to create the structure of the team/commission structure before they could give an official offer." In the following weeks, I followed up routinely as I would told it wouldn't be long until I received the official offer - and I was not going to give notice to my current employer without something in writing. Then as 1-2 MONTHS passed, no response. They completely ghosted me. I've never experienced anything so unprofessional, I was so excited to start the role and had a great experience up to that point but was very disappointed in this company that seemed very promising.
