I applied online. I interviewed at Proofpoint in Sep 2017
Interview
Had one round of phone interview with some system design questions and REST API. After this went well, went for the on-site interview. Complete BS. One abhorrent Architect, extremely rude, would cut every little thing I tried to say, claiming he wanted to save time for my benefit. He asked a typical sort question, "limited RAM, humongous data set, how do you sort". Looks like he was predetermined to mess with me and the conversation went nowhere.
