Initial phone call with HR. Second interview was with one engineer. This interview consisted of reviewing my experience as well as technical questions. Third interview was panel style with a coding assessment provided to me prior to the interview. They asked to explain my code and how I would modify it given various scenarios.

Initial 30 minute phone screening. Second interview was an hour going over my previous work experience and technical questions that consisted of OOP fundamentals, pointers & references, mutex locks, TCP vs UDP, virtual funcitons

Initially was supposed to have a 30 min phone call with the recruiter, but ended up starting with an hour long video interview with two engineers instead. Questioned me on basic CS concepts (TCP/IP, concurrency, race conditions, heaps & stack, etc.). This was followed by a 2-hour long interview with the panel. Went over some behavioral questions and then 2 brainteasers and 2 easy LC questions. Overall I felt that I did well in the two rounds as I had answered all the questions pretty well, but I was not selected.
