How Can I Prepare for My CDN Sysadmin Interview Next Week?

Trying to cram years of experience into just four days is a tall order! Just a heads-up, if you're not familiar with Varnish, you might run into some challenges, especially if they expect you to troubleshoot specific instances. My advice would be to focus on hands-on tutorials and labs. It’s one of the best ways to pick up these technologies quickly. Don't just go for Docker Desktop; instead, install Docker Engine directly. It’s better for understanding how Docker operates in an enterprise context. Look up how to write Ansible playbooks to manage containers effectively and practice a bunch of Docker commands. Also, make sure to spend some time learning about Nginx since it can be quite versatile and complex. Good luck!

If they're aware of your limited experience, don't stress too much about it. Focus on understanding the general concepts of caching and how it works. Dive into system performance aspects critical to CDNs, like load averages and disk I/O. Also, brush up on everything related to HTTP, especially SSL, different HTTP versions, and proxying. Having even a basic knowledge of these topics can give you an edge during the interview. Remember to prioritize understanding over memorization—this approach works best in interviews!
