I applied online. The process was relatively quick, since they were actively looking for SRE candidates.

The process started with a phone screen with a recruiter. This was followed by multiple interviews over the course of a single day onsite.

There's a remote machine that needs to be updated. The problem is, the machine overheats during the update. How do you perform the update without overheating the machine?

This is a D&D-style scenario, where you have to troubleshoot a broken system. You describe your method of troubleshooting and what tools/commands to run, and I will respond with the return value of said tools/commands. The overall point of this interview was to gauge the candidate's ability to triage issues that arise.

You have a site that gets increasingly popular. Whiteboard the system architecture and how you'd scale it up as your site gets more users.
