Expedia Group Software Development Engineer interview questions

Spoke with recruiters at university career fair. Got a "call-back" later that day to set up an on-campus pair white boarding interview for 8am the following morning. Later that week heard back for an online HackerRank challenge. Took them a long time to respond after this but got the offer after a phone call (just a "what are you looking for"/"this is what our program is like" phone call). Pair whiteboard-ing: One interviewer and 2 interviewees in a room with a whiteboard and markers. Interviewer read question and evaluated both your solution and collaboration. Was told at the start we were expected to get through about 2 problems. Found out later that my partner and I were the only ones to get through two problems. One was about the difficulty of a hacker rank medium and one was a hacker rank hard. HackerRank technical challenge: Usual deal. 60 min, 2 questions. One was about a HackerRank medium and one was ridiculously easy.

Four rounds -> three technical, one behavioral. One technical round was testing and the interviewer was vague and she asked about weird test cases without considering the use cases. She wasn't willing to listen and was unreasonable. The other two interviewers were great and asked reasonable questions.
