Next, there is a cross-functional interview with a manager, which involves traditional behavioral questions, such as how you resolve conflicts with colleagues or your manager.

The final round is a system programming interview, covering multi-threading knowledge and coding. While compilable code is not required, precision in syntax is expected.
