Campus interviews involved one-on-one sessions with whiteboard coding. The problems were simple, utilizing binary search tree traversal and binary search for a given scenario. The interviews went well, and I received an invitation for onsite interviews at Expedia's Bellevue HQ. It was challenging and fun, with three back-to-back interviews. Two of the interviewers were amiable, while one was uptight and hardly smiled. Expedia is quite generous in reimbursing travel and lodging costs, offering $75 per day for meals.

I received the offer within 10 days. The pay rate is the best part, exceeding expectations. The whole process was quick, efficient, and enjoyable.

1. Given a series of data, cluster it into sub-components. This was for a specific use case that was fun to solve. Prepare the HashMap well.

2. Given two rectangles, find the smaller rectangle formed by their intersection.

3. Given a 2D matrix filled with 1s and 0s, find the number of connected components of 1s.
