TGS Management Company interview questions

Responded to a cold email from a 3rd party recruiter they hired to scout LinkedIn, quickly moved to phone screen with the company own recruiter. There was a lot of rounds with a lot of people, the whole process took almost 2 months. They were quite pleasant to talk to, smart, interesting problems, very positive towards the end, but a bit too relaxed and calm for my Bay Area taste. Cons: it seems they were open towards remote role, but later in the process I learned that I need to move to Irvine. I'd preferred to know that in advance. This 2 months long process ended up in ghosting. Extremely unprofessional. They are probably so old and small that they forgot how to hire in the 21st century.
