Manager round (comprised of technical questions, background and work experience, and coding problems) + 4 Virtual Onsite rounds.

Overall, the interview was decent, but some questions were beyond my scope/knowledge. For staff-level roles, they do expect very specific domain knowledge.

Here's a list of topics:

• Pointers: how to allocate an integer pointer.
• Synchronization using Mutex.
• Mutex vs. semaphores.
• Smart pointers in C++.
• Lambda functions in C++.
• Merge Intervals -- LeetCode.
• Design a phonebook.
• What is your experience with performance counters?
• What are the types of overloading?
• API vs. ABI.
• How do you typically handle a performance issue?
• What is template specialization?
