Devops Hiring (But Also Some Generally Applicable Advice)
Uri CohenHead of Product @ GigaSpaces
@uri1803
"5-7 years of devops experience"???
"Practical experience with most if not all AWS components"???
"Hands on experience with monitoring tools, intrusions detections mechanisms…"
And it goes on...
What's Wrong Here?
"Operations Engineer" is a new profession
DesignMaintain
Analyze
Monitor
Build
Automate
complex, large scale, highly available production
environment
"I'm looking for candidates with a degree from a major university"
Is there an institute in which you can learn how to monitor a system?
I want someone with at least x years of experience in…
4 is better than 2?
Can't someone be really bad with 5 years or experience?
What's the Right Answer to These Interview Questions?
● "How do you configure a GRE Tunnel in Junos"?
● "Which port does Kerberos require"?● "How do you move a zone file between DNS
servers"?● "How do you configure an F5 load balancer
to route traffic to the least busy server"?● etc etc etc
What's Wrong with This CV?
(assuming there's someone who can actually learn all of this in less than 4 years)
Does It Indicate If the Candidate Can:
● Apply the right tool to a problem?
● Learn a new tool when it's needed?
● Solve a problem, any problem?
● Identify there actually IS a problem?
Look For:
● Passion and willingness to learn● Problem solving mentality● Self motivated individuals ● People that are fun to work with
Tools and experience are important, but are not the only, and certainly not the most important factor
