I applied online. I interviewed at Google in Jan 2019
Interview
Quite smooth, good communication with the recruiter, good planning, not so good outcome. I went through a first contact with the recruiter, filled a questionnaire and then we schedule a phone technical interview with a data scientist. The job was originally for a position in Zurich, however I was interviewed by a statistician in Mountain View.
Interview questions [1]
Question 1
Question on the use of p-values in high dimensional linear regression.
The standard interview process starts with resume screening, followed by initial phone screening, technical and behavioral rounds, a final leadership interview, and ends with reference checks and a job offer.
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.

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
