I had four interview rounds on the same day.

These consisted of one system design round and three rounds with coding problems.

The interviewers delved very deeply into the behavioral questions, so it's essential to be well-prepared for follow-up questions in that area.

I found the coding problems to be slightly more difficult than I expected.

There were:

• Two medium-level problems
• One difficult problem

Additionally, the follow-up problem for one of the medium-level questions was quite interesting and challenging, making it not easy to come up with a solution.
