Extremely thorough - 8+ rounds of interviews. All of the interviews were technical, usually consisting of 1 coding (leetcode) question and a few math questions. The math questions were usually brain teasers or expected value questions.

Interview
I went through a total of 3 rounds of interview. The first round is only 1 hour with 1 person where I was asked first a pen-and-paper algorithm question, and then after I was asked a coding question. Then the next two rounds are with 3 people each in the same format. The interviews get increasingly more difficult as I proceed through the rounds.
