And how about people who have a job that they just don’t like that much, and would love to escape.

Having 9 rounds of interviews sounds crazy excessive. Why is the 9th interview needed that you couldn’t have figured out by the 8th interview? If regular companies do that, I opt out, it’s a don that they are delusional, inefficient, incapable of making decisions and don’t respect candidates time and potentially different life circumstances (candidates might have family, full time work, hobbies, other interviews).

On the other hand, their company is quite unique, I bet they have enough applicants, so in the end it’s supply and demand, and companies in extreme demand can make their interview process as tiring as they wish…
