Mostly based on your resume. But broadly from Linux, Python, Terraform and AWS. Some in kubernetes (interviewer asked me if I'm comfortable with it then kubernetes depth increased). Few i could remember:
1. How do you troubleshoot website sloweness?
2. Trouble shooting disk, cpu and memory high issues - had in depth questions
3. How do you deploy for 1000+ servers
4. Deployment issues in troubleshooting
5. Design an infrastructure for given stack
6. Script in python
