Applied through a recruiter and had my first-round interview as a phone screen using HackerRank. The question was a LeetCode easy problem concerning recursion.

Had my second-round interview, which was then three back-to-back interviews with different engineers. The final of the three interviews was with two engineers. The questions revolved around string manipulation.

Didn't make it past this round, but I would say the process is very straightforward and I would focus on LeetCode Medium level questions as that is the level of questions you're most likely to face.

LeetCode easy to medium problems.

The engineers made the problems themselves for the second round, but it seems like they ask a lot of string manipulation problems.
