I applied online. The process took 3 weeks. I interviewed at Signifyd (San Jose, CA) in Feb 2018
Interview
There was a phone screen, a technical coding challenge and 4 hours of onsite interviews. Very standard process for a software engineer position. Recruiter and HR were very friendly and helpful. Interviewers were professional and easy to talk to.
