Expedia Group Software Developer interview questions

It was a coding challenge - 1 easy LC, and the other hard to medium LC. There were multiple choice questions on some basic Data Structures stuff. I thought I had aced the challenge but I was still rejected.

It was an off-campus interview. There were two rounds. The first round consisted of system design questions and was asked to create a website similar to Expedia. The second was the DS- Algo round where two coding questions were asked.
