I applied through their website.

Got an email the next day offering a HackerRank test. Then I had a phone call with a recruiter, and on-sites were scheduled for the following week.

The on-sites lasted from 9 a.m. to 6 p.m., with a succession of one-hour rounds and a lunch with part of the team in the middle.

The questions were interesting and challenging. Everybody was nice and smart – the interviewers were helpful, and it felt like they wanted me to succeed. The whole experience was very pleasant.

I received a phone call from the recruiter congratulating me and telling me they would extend an offer. The offer came a week later.

HackerRank 3-hour online test.

One question boiled down to a BFS, and the other was a dynamic programming problem. The whole thing was easily solvable in less than 45 minutes.
