I applied online. The process took 2 months. I interviewed at Expedia Group (Bengaluru) in Feb 2026
Interview
The interview experience was positive overall. The interviewers were understanding, supportive, and created a comfortable environment for me to share my thinking. The questions were thoughtful and relevant to the role. However, the process was significantly slower than expected — there were long gaps between rounds with little proactive communication, and I had to follow up multiple times to get updates on next steps. Faster communication between stages would greatly improve the candidate experience.
Technical phone screen and then 4 rounds of interviews that covered machine learning, coding, and soft skills. They let me know they were not going to make an offer several weeks after the interview.
