The first round is about checking out your real-time problem-solving skills. They give you their codebase and ask you to find a bug or add a new function right then and there. It's a plus if you're used to working with large codebases.

Coding Technical
I went through 2 interviews. The first was a standard algorithms and data structures interview where I had to solve one problem that had 4 subproblems and didn't require any specialized knowledge. The second interview was pretty cool, involving a real-time implementation of a small feature within an existing codebase. It mainly tested my ability to search and understand code dependencies. Everyone I met was really nice and helpful.
Confirmed questions1 question
- Regarding hash map implementations, what are the strategies to avoid collisions?
