I applied online. The process took 8 weeks. I interviewed at Google (Zúrich) in Jan 2019
Interview
Technical Interview focused on statistics. It is strongly focused arounds stats rather than technical programming. They check your knowledge and reasoning process.
Hangouts conference with one data scientist, very friendly guy that opened a conversation around experiments and statistics.
Interview questions [4]
Question 1
I have a deck and take one card at random. What is the probability you guess it right?
Then I give you two questions and you can only ask one:
a - is the card red
b - is the card 10 spades
Which one would you ask and why?
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.
