There were 3 rounds in total, process within 3-4 weeks in total.
First-round was with HR and witch basic questions. The recruiter was very nice.
Second-round was online testing, with a coding problem, debugging problem and a logic test, within 70 minutes in total.
Final round is with the recruiter, VP of Engineer and Tech lead. I was introduced to the product, the company, and was asked numerous JS questions. IMHO, the difficulty of those questions is average.
