1 initial phone screening with a recruiter that stays in touch with you throughout the entire interview process. Following that there were two more rounds of interviews over zoom. The final interview was meant to be in person though so be prepared for that. Everyone that interviewed me was extremely kind. I didn't feel scared at all to talk to them and the conversation flowed very naturally. I did about 50 interviews in the span of 4 months and HUB was by far the most stress free. The entire process took about a month.
