Overall, quite straightforward, as many other posters note. The process formally starts with a code screen, moved to a phone interview, and then on-sites.

Overall, the questions can be challenging at each part, with the on-site interviews being a case of 'your mileage will vary'. The interviewers may select DP problems, graph problems, and are likely to be interested in your thought process.

Specifics are under the non-disclosure agreement, but one that I kind of stumbled upon turned out to be (I'm pretty sure) a DP problem, which I initially tried to solve greedily.
