Interviewed with an Engineer, and the Director. Super bad experience. I interviewed with over ten top-tier tech companies, and they aced the worst experience to me. Their technology is just in regular level, the same as many other small ones, but I don't know why they are super confident, and even arrogant for themselves during the interviews. They said like "our team is all Phds, and we don't hire others'", while in fact I know many masters and even bachelors there. They mentioned they need very solid technical guys for the Data Science, but cannot really say what specific part they are looking for, and comment me as "what technics do you really know?"... Excuse me? Just my 'poooor' ability brings me a lot top results in many competitions. I don't know what person they want for an entry-level with 70-90 thousand a year. Pretty Silly data science team. I cannot imagine the life there, and I would never recommend to join them.
I applied online. I interviewed at Expedia Group (London, England) in Feb 2026
Interview
First technical assessment: 75 min for Hackerrank generated questions, related to business scenarios that Expedia normally would encounter. multiple SQL Qs + 2 Python Qs + Basic 101 Stats (p-value, type 1, type 2 error, CI)
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.
