It's quite a lengthy process with about 8 steps in total: initial talks with a recruiter, a coding challenge, a legacy coding challenge, a Tao interview, system design, wraps, and talks with the CEO. In my case, the interview spanned two days, which I requested, or you can choose to do it in one day. The interviewers were very supportive throughout the entire process and made things easy. Despite this long process, I didn't feel overwhelmed.
