I applied online. The process took 2 weeks. I interviewed at Springbox (Austin, TX) in Mar 2015
Interview
After sending my letter and resume I was called within a couple of days. We set up a phone interview which lasted about 15 mins. A day later I was asked into the office for a 1:1 interview. The questions were straight forward, and overall it was a pleasant interview. The response (they had hired someone else) from that took about a week and a half.
