I applied through a recruiter. The process took 4 weeks. I interviewed at Emerald Cloud Lab (San Jose, CA) in June 2020
Interview
1. HR contacted
2. A super long written exam (like college problem sets)
I don't think it's valuable to spend time on the written thing. The whole process is not professional. Please don't waste your time.
Interview questions [1]
Question 1
Questions about Physic, Chemistry, Statistic, Algorithm and lot of others.
