This is not:
My experiences from >gt;4.5 years
Written by HR or PR
A culture worth sharing
An official guide
(This is: https://jobs.netflix.com/culture)

Experience: Job Interview
It sounded too good to be true
I asked many questions,
trying to find the catch
(there wasn’t one)

about employment

Worst thing for me at Netflix:
When we run out of coke zero in the F2 fridge
I can either walk down to the F1 fridge, or up the F3 fridge...

Worst thing for me at Netflix?
Too many
awesome things
to work on, not
enough time
eBPF tools
PMC analysis
Kernel performance
JVM internals tracing
Distributed systems
Flame graph differentials
eBPF latency heat maps
Perf training courses

Netflix, F2, 5:30pm on a Wednesday
… that doesn’t mean we work long hours

encourage independent decision-making by employees

keep only our highly effective people
avoid rules

Particularly selfish jerks, who may:

Only support self-promoting tech
Become a negative role model
Damage includes:

Demoralized staff & turnover
Company inefficiency
Netflix staff are respectful & supportive
