I applied online. I interviewed at Zscaler (San Jose, CA) in Aug 2020
Interview
3 Rounds of phone interviews. Recruiters were friendly. The engineers were late for the interviews (15 minutes and 1 hour). Interviewers did not seem prepared. Postponed final decision repeatedly (got an answer after a month of the promised date).
