I have a sysadmin interview tomorrow. Anything specific i should know?

Don't forget, the computer is under the table. On top is just the monitor.

Oh, and if there is fire, just put it to the other fire.

backups, HA/HP clustering, DR, security, hardening, edge, automation, patching, scripting, UNIX vs linux (assuming a *nix admin role), network stack, tunnelling/IPSec, monitoring/alerting, vendor cases, pixie-boot for parallel provisioning, virtualization (vs containerization), hypervisors, resource mgmt, swap vs ram, performance troubleshooting, SAN, NAS and their implementations (examples), use cases, how different, replication in DC / across DC, network routing, A-A vs A-P clusters, firewall/NAT configuration, network protocols (IP, UDP, ARP, DNS, HTTP, TLS, ICMP, SNMP), how traceroute works,...

just refresh your memory on those few topics and you should be good IMO.

Try turning it off and on again. If that fails, try turning the things it talks to off and on again.

Give the devs access to everything, otherwise they will go digging around and you will have more problems in the long run.

If they ask a question you don't know, simply respond ..."Pffft...that's a stupid question. Next."

Just hope the interviewer didn't use the same tactic when they got hired. :)

Joking aside...good luck and respond with how the interview went.

SRE is still all the rage be prepared to answer something about that.
