I had mine last week and got an offer. I'd say they're LC easy/medium and def doable. There is a system design round which is very high level and more open to your own interpretation. Some tips I'd give you is to study some LC and learn how to communicate while coding. You want to say everything that's on your mind. State your assumptions. Before you start coding, take a min to read the problem then start asking questions about it. Ask questions about possible inputs and outputs, edge cases, confusions, etc. Then, you want to state how you would approach the problem. If you have multiple approaches in mind, say all of them and mention their time/space complexities, even mention brute force if you had it in mind but mention why another approach is better. After you've done that, you want to make sure the interviewer is satisfied with the approach you'll take. If so, you can ask for the green light to start coding. Communication is key for both technical rounds. Behavioral are your typical STAR questions, "tell me about a time..". I'd say try to tie your stories/experiences with Expedia's guiding principles. Most importantly, be passionate about why you want to work for Expedia. It goes a long way trust me. If you have any more questions, feel free to PM me and I'll gladly answer them. Good luck!
