I applied online. The process took 4 weeks. I interviewed at Palantir Technologies in Feb 2015
Interview
Applied online and waited a couple of weeks. Then I received an email for a coding challenge with one problem in 90 minutes. The problem is hard and I didn't come up with the optimal solution. A few days later, I received the reject email. It is so far the hardest problem of all my interviews.
Interview questions [1]
Question 1
Flipping columns of a matrix to get maximum benefit
Recruiter screening call, gauging interest. They were mainly interested in learning more about me, and how my expericnes may align with the role and company. Got the interview before any online assessment was shared, directly after a cold application.
After filling out essays on their application, I was sent an email outlining potential topics for the technical interview, as well as advice on preparing. The Interview was conducted with someone from the platform Karat. Was very smooth and the interviewer was very skilled, and they even offer a redo if you are not confident

Process was long and drawn out, with multiple different rounds of interviews. After the onsite, I had another interview with a hiring manager where he asked me even more technical questions.
