Initial screening with HR. High-level chat with an SE regarding experience and a few easy domain-specific (C++ in this case) questions. Two 1-hour technical interviews involving some coding and problem-solving. Lastly, a fit interview focusing on interpersonal skills.

All interviewers were very friendly and would help the interview along if things got a little stuck in places.

Be sure to talk through your thought process when breaking down a problem.

Good familiarity with C++ is a must, especially object lifetimes (when various ctors/dtors would be called). Know your algorithms and data structures – not just how they work, but what considerations they would have (performance, memory usage, stack usage, etc.).

The application was for a C++ role.

Technical interviews included high-level architectural questions (how to approach a large feature), code review, and lower-level problem-solving (write a function/class which does X).
