I applied through a recruiter. I interviewed at Google
Interview
Hangout interview was right on time, fair questions, the very nice guy from Germany, asked mostly about my previous experience and academic background. As I see it, the goal was to understand the extent of my knowledge in statistics and machine learning, also how I draw conclusions and interpret the results of my research.
In the technical round, I faced a challenging A/B testing question regarding YouTube thumbnails that pushed my analytical skills. I was also asked to discuss metrics for evaluating user engagement, which had me thinking on my feet. The behavioral section was tough, but I found the principles I studied on PracHub to be incredibly relevant. The overall experience was intense and demanding, yet I received an offer in the end. Ultimately, I decided to decline, as I felt it wasn't the right fit for my career goals.
Interview questions [1]
Question 1
Design an A/B test to evaluate the impact of a new YouTube homepage thumbnail design on user watch time. How would you choose the success metric, sample size, and handle novelty effects?
It was all good, the interviewer was very nice. Technical questions were a bit challenging but overall it was good. The hiring manager was looking for some hands on experience
I applied online. I interviewed at Google (Mountain View, CA) in Apr 2026
Interview
Got email from the HR and scheduled 2 virtual onsite interviews. It went well. I went through another 3 rounds of VO. My packet was submitted to the committee. They do not like it and gave me another round of VO. In the 6th round VO, my application got rejected. It was a total waste of time for everyone.
