Expedia Group Software Engineer(Internship) interview questions

I had 3 back to back interviews in a 4 hour time period. Was given leetcode mediums and easy behavioral questions. I was also told to design a class using OOP principles.

It was a coding test that was online which was 1 and a half hours and tested on multiple choice as well as a couple of programming questions on some simpler algorithms. Then there was a final round that consisted of 3 rounds.
