I applied through an employee referral. The process took 4 weeks. I interviewed at Google (Mountain View, CA) in Jan 2020
Interview
Overall the process is very smooth and well-explained. First interview is a phone screen with a recruiter who will walk you through Google's interview process. Next step is a 4-part technical screen lasting an hour:
1) Describe a past project
2) Stats question
3) Causal inference question
4) Coding question
After that it would have been onsite interviews but I didn't get to that stage. Generally speaking, the types of questions asked were not only more difficult, but also it felt as if the bar was also higher. Positive experience overall, but difficult interview.
Interview questions [1]
Question 1
One question about computational statistics, one question about causal inference, one coding question
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
