I applied through an employee referral. The process took 2 weeks. I interviewed at Proofpoint (Sunnyvale, CA) in Oct 2017
Interview
30 minute phone interview with hiring manager. Followed by an in person interview with 3 managers and potential co-worker. No feedback regarding job even after 1 week. I eventually realized no offer would be forthcoming.
Interview questions [1]
Question 1
