Initial test for 3 hours. Felt like real world problem solving based on Graphs. You can find details in other reviews. 45 mins phone call interview with Senior Engineer and Manager. They were more interested in your keen to learn new things. Polite and welcoming interviewers. 4 hours of onsite rounds covering Data Structures and Algorithms, System Design and Resume walkthrough. Pleasent folks and they do provide hints if required.

I applied online and they emailed me a coding test which I had to complete over two weeks. This was the hardest coding test I ever took in my job hunting journey. It was 2 hours 30 minutes long with the first session being 1 hour 30 minutes long and the second being 1 hour long. The first part basically have you design a data structure to solve a problem and provide your reasoning behind it. The next two questions are based on your first design and ask how would you modify it if the situation changes. The second part was actually implementing that data structure I discussed in the first part. Overall, very hard, but a good learning experience. I obviously failed miserably.

Started off with an online assessment with 4 parts. The first 3 were describing how you would implement the solution to a problem and discussing runtime and trade offs, and the final part was coding some of the solution you described. After passing that, I then had a 60 minute phone interview with an engineer. Talked a bit about a past project of mine, then spent the last 45 min solving a system design question together. The on-site consisted of 4 hour long whiteboard coding sessions and lunch with 2 engineers. The questions were fairly straightforward, with the usual mix of tree, hash table, etc questions. The interviewers gave hints pretty frequently, with an emphasis on how you took the hints over whether they needed to give you one. Overall, I found each interview to be a really pleasant, collaborative experience. Definitely the smoothest interview process I’ve been a part of.
