I applied through college or university. The process took 1+ week. I interviewed at Voltabox (Austin, TX) in May 2016
Interview
I had two interviews, the first with Head of Product Management. The questions were somewhat technical but easier than most interviews I've had. I had a follow-up interview with the COO immediately afterwards. He explained the position in greater detail and asked much broader questions pertaining to my long-term goals.
