I applied online. The process took 4 weeks. I interviewed at Google (San Francisco, CA) in Nov 2023
Interview
I had a series of technical interviews. These were conducted over Google Meet. Each session was with a different interviewer and lasted about 45 minutes. I was asked to solve coding problems in real-time, focusing on algorithms and data structures. One of the interviews was more focused on system design, where I had to design a scalable system and discuss various trade-offs.
The questions required me to think on my feet and demonstrate not just my coding skills but also my approach to problem-solving and my ability to communicate my thought process clearly.
