I applied online in October 2015. In December, I received an email from a recruiter asking for my preferred date and time to schedule the first technical phone interview, which I attended in January.

During the interview, I was asked a couple of algorithm questions. I took a lot of time to solve them, and the process lasted the entire interview. The interviewer was very nice and provided useful hints to reach an optimal solution. At the end, I managed to solve the questions but did not receive a callback for a second round.

I asked for feedback, and the interviewer responded that the questions were not that difficult and shouldn't have taken me so much time. They also noted that I wasn't accurate with my coding (I did fumble with the code initially). In my opinion, I didn't do too well in reaching the optimal solution; I sort of stumbled upon it.

The recruiter was very nice and prompt in responding to emails throughout the process, and the interviewer was genuinely helpful.

Both questions were related to algorithms and data structures.
