I applied through an employee referral. The process took 2 weeks. I interviewed at Pindrop (Atlanta, GA) in Jan 2016
Interview
After a couple of phone interviews (both with recruitment as well as technical people) I had to come to Atlanta for an onsite interview day. During that day there were four interviews: Signal Processing, Machine Learning, Programming and an interview with the VP of Research.
