Expedia Interview Experience

I applied to Expedia for SDE2 role (with 3 years of experience) through LinkedIn. Here is my Expedia Interview Experience.

Round 1

Hacker-rank Assessment Test. This was the screening round. Questions was easy to medium level. All test cases must pass to go for next round.

Round 2

This was 1 hr coding interview round. 2 coding questions were asked in this round.

• Iterative Post-Order-Traversal of a binary tree. I gave the solution using 2 stacks. Interviewer then asked me to optimize the space complexity. So later I came up with the one stack solution.
• Merge the contagious duplicates to single one in the list and return the new list. Ex: If the list contains elements like : 1,1,1,2,3,3,1,1,4,4,4,5,2,2 then the resultant list should don’t have contagious duplicates. i.e the resultant list should be: 1,2,3,1,4,5,2

Round 3

This was again a 1 hr coding interview round.

•  Convert Sorted Single Linked List to Binary Search Tree

It took me 55 minutes to solve whole problem correctly. So time was up!! Mostly they ask 2 coding questions in 1 hr of interview. I thought that I would not be getting call for next rounds. But after 2 weeks they scheduled the next 2 rounds( technical non-coding round and managerial round)

Round 4

This round was non coding round. It was more about the project I mentioned in the resume and the tech stacks used in the project. Interviewer asked me lots of questions on Java, Spring Boot concepts and other tech stacks. Some of questions which I remember are:

• Multi-threading questions like: What is future, atomic, executors in Threading concept.
• What is AOP in Spring boot. It’s uses and why. And some security based questions around this.
• Situation based questions. Like what technologies you will use if to counter any problem.
• Apache Kafka concepts.

Most of the questions were situation based. You would have to come with the solution to tackle those situations.

Round 5

This was managerial round. This was the project and architecture round. Interviewer asked lots of questions around the project I mentioned in the Resume. Project architecture and the tech stack I used and why. Some behavioural questions.

Thats all my Expedia Interview Experience for SDE2 role. After 2 weeks I got the offer letter 😀
