Does anyone know what the interview process for a systems engineering job is like at Jane Street?

Are the phone interviews similar to the quant or trader interviews? (mental math, probability, brain teasers)

I actually read those, aside from the "...and SIG" thread.

I mostly was wondering if the sysadmin phone interview is the same as the quant/trader phone interviews I've read about. I.e. are they going to ask mental math problems, or ask about unix/networking arcana? This probably is the wrong forum to ask, but I've not yet found a "sysadmins in quantitative finance" forum.

With my apologies for thread necromancy:

Had an interview, closer to 2017 than 2011. It's like the Glassdoor reviews say. To them I can add:

No math problems. Know your Linux syscalls. Know how the different parts of an OS work internally, even better if you have an opinion on their design that is backed by arguments. Know what failures can happen to networked services and how to mitigate/avoid them.

On the other hand, they seem to have little interest in the fluffy stuff (configuration management, containers, ...).

You will also get tested on your programming skill at a basic level ("basic" for their programmers, that is). Know how to design a small piece of code correctly, including dealing with concurrency issues.

I wish all my interviews were on that level.
