I applied online. I interviewed at Proofpoint (Sunnyvale, CA) in Sep 2020
Interview
I was schedules for a virtual onsite interview (4-5 rounds). However, after 2 rounds, I get a call from recruiter informing that all other rounds have been cancelled. Overall, dont waste your time here. The interviewers are rude. They lack a professional process. The coding questions was easy however they keep trying to get your moral down. The JD said the following ( I guess they really mean it) :
Low ego and someone who puts the team and the organization first. You have strong opinions that are loosely held.
Even if you get a offer, think before you join the team.
