Interview
I applied through an employee referral. This was for an intern position. I did two video interviews. The first one was purely technical, while the last one was with the team that wanted to hire me. The latter was more personal and they wanted to know more about my research and past experience.
Interview questions [2]
Question 1
I signed an NDA, so can't give all the details. First interview: There were essentially typical probability questions about confidence intervals, sample size, and hypothesis testing. Some questions were longer so they gave you a problem with some data and you had to argue how you would estimate an effect or design a better way to estimate it. There were also basic coding questions about manipulating data and running MC simulations.
They asked me to go in detail on certain research projects and work experiences, and asked me why I chose that particular methodology, what difficulties I found, what would I have done if I had a different data, etc.
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?
Email-phone-onsite
The HR are very slow and extremely hard to work with. They asked for my availability for the phone interview (1h), and I gave them five full days to choose from. Result is, they gave me a slot that's not on my availability list.
