It started with an hr interview, than I had 3 hours technical interview, which splitted to 1 hour for each interview, each one was a diffrent interviewer, 1 question was about system design, 2nd was leet code sytle question, and last was understanding existing code and implementing change

First a phone call, where they explain about the position and ask about experience and check suitability. Then a technical interview, if you pass, another technical interview. The interviews are not in the same day.
