Expedia Group interview questions

I got selected after aan online assessment. There were 15 of us. There were two rounds of OAs. In my first interview the interviewer focussed heavily on my resume. We had a 30 min discussion on my projects and what all AI models could I use in my project. After that he gave me two dsa questions. One was based on sliding window and the other was based on string comparison. The first one was leetcode medium and the other one was easy. In the next round there were again two dsa questions. One was based on stacks and the other was an array problem. However this second question was of hard level and I couldn't figure out the optimal solution. I solved 3/4 questions but didn't get selected. Only 5 students were selected from our campus.
