It was relatively smooth. They interviewees are kind and will help you through the problem. You should know your computer science basics. And In terms of difficulty, I'd say two LC mediums.

The interviewer didn't focus on what was required. I had made a project which had an AI integration. He said we aren't hiring for AI related roles. Also my major was in IOT and cyber security. he told me to pursue IOT. Which was not professional at all.
