I applied online and then received an OA from the recruiter. I don't remember the exact number of questions, but they were combined: two coding questions and some multiple-choice questions.

One coding question was in Java. You needed to delete nodes within a linked list where nodes had a certain value. The second coding question involved finding a bug in C++ code.

The multiple-choice questions were about algorithm fundamentals, like time complexity. The OA was not difficult.

Then, I received a phone interview. This interview focused on multiple inheritance classes. You needed to figure out the memory layout of objects of multiple inheritance classes in the compiler.

The interviewer and HR were very nice. The interviewer provided hints when I was stuck.

C++ virtual functions: you need to know something about how virtual functions are implemented.
