I applied online via LinkedIn. Their recruiter contacted me after 6-7 days and scheduled a phone call.

It was surprising, as the recruiter asked somewhat technical questions (like most challenging project, complicated bug, etc.).

Then another technical phone screen was scheduled with their hiring manager.

After that, onsite interviews were scheduled. There were almost 7 interviews (4 technical, 3 behavioral types with a Director, VP, and the hiring manager).

Technical questions were a deep dive into algorithms, data structures, 2 whiteboarding problems, and architecture design.

Overall, I believe it was almost the same as other tech companies in the SF area. The team seems smart, and they asked good questions.

As per the NDA, I can't mention all the questions. However, most questions were related to graph theory, tree traversals, recursion, design patterns, and string manipulations.
