Expedia Group Back End Developer Placement interview questions

My interview has 2 stages, one was online coding exercises, other was assessment day in the office. The first part was standard Hackerrank tasks, two questions, you can choose languages. The second part was in their office and contained 2 parts - technical and group exercise. Interviewers and people who helped during the day was very helpful and friendly. At the beginning of each section, we had some 'icebreaker' to meet with team or interviewers.
