A pretty standard process, with at least 5 stages involving all relevant stakeholders, including your future direct colleagues.

Expect at least 3 fully technical interviews.

Everything is conducted online.

Details for pretty much every interview are shared beforehand, so you will have a good understanding of what to expect.

Quite a few things are written with C++ in the company, so you'll find everything you'd expect from real work:

• Language features
• Containers and the standard library
• Concurrency
• API and system design

Every interview starts as an open-ended problem, so it's not straightforward to solve like any simple coding or algorithm question. You'd need to know your stuff, but you will be safe if you've spent some 5-10 years really working on complex projects. Simply grinding LeetCode/sysdes is only partially useful.
