I applied through college or university. The process took 1 day. I interviewed at Quantum Reservoir Impact (Austin, TX) in Oct 2016
Interview
I was given ten minutes to code in Matlab, which I did not finish. There're also some questions about my research experiences. Overall, the technical part was definitely challenging. But the interviewer seemed nice and made me feel comfortable even though I didn't think I did well.
The interview was conducted over Skype. The questions asked were ranging from technical to behavioral related to research, coding, teamwork, communication skills. The interview lasted between 45 minutes to 1 hour. There were two interviewers.
