Start off with a phone screen where they ask simple questions about your background and resume. They will also ask simple programming principles and concepts(Difference between stack and a heap, multithreading, etc). Secont Interview was pretty brutal... it is a panel interview where there is the first round that asks for your background and a simple coding interview in Python. Second interview involves C++ and is alot more involved in that you are tasked to create a project from scratch. The interviewer was not helpful at all as asking questions to the interviewer would only annoy him, as he would only tell you that the description of the problem is in the chat. Interviewer was not helpful in helping you with the problem.
