I applied online. The process took 2 weeks. I interviewed at Google in Jan 2015
Interview
Applied through a referral from the company. Great experience - cool people, stimulating interviews, very efficient HR.
Two coding questions on phone interview - one on adding integers of arbitrary size and another that I can't recall.
On-site interview entailed 5 back-to-back interviews and lunch.
1. Talk with a manager and question regarding TCP Path MTU discovery - black hole connection.
2. Others were whiteboard coding and design questions. Study up on algorithms and data structs!
Interview questions [1]
Question 1
Phone screen: the troubleshooting scenarios were typical things I'd seen in my 10 years administering a large network of Linux machines. For the coding exercise I chose Perl because that's my best language and as a result I had to explain some of the code to the interviewer (I think Google uses mostly python).
HR round after applying, then coding screening round, if passes, then final round which consists of four coding round or three coding and one design round. Problem difficulty medium to hard.
I applied online. I interviewed at Google (Zürich) in Mar 2026
Interview
Frist had one roughly 20 to 30 minutes screening call with a recruiter, then had one online 45 minutes technical interview with a Google Site Reliability Engineer. The technical interview covered data structure and algorithm topics.
I applied online. I interviewed at Google (Dublin, Dublin) in Mar 2026
Interview
The interview lasted 45 minutes and was conducted one-on-one. I was required to walk through my thought process before coding and then implement an optimized solution with a focus on time complexity.
