I was given a question papaer with 20 c questions, basic syntax errors, data structures etc were asked, all were fill in the blanks or descriptive type of questions. The topics also covered Networking, OS, Arcitecture and debugging.

onsite interview with 2 team members two hours long. after a short call with hiring manager. nice people, asked me about my experience and to present something from previous work place. after that came the technical questions. finally I get to ask them about the job

took 4 rounds of interview, 3 leetcode question, 1 system design. The leetcode question is pretty standard, but the system design question is hard. It took more than 1 hour for that round.
