Applied through the recruitment firm. The process described included a 1-hour technical phone/Zoom screen and a 4-hour onsite interview. I didn't make it past the technical screen itself, so I can't comment on the onsite experience.
The technical screen question was a LeetCode hard question, and I honestly didn't expect that during a tech screen. I was only able to provide a half-working solution and explain my thought process on how to solve it, but that wasn't sufficient for me to move on to the onsite.
If you are applying, be prepared to answer LeetCode hard questions (even during the tech screen).
