Any good resources to see how they interview for SRE-SE? For SWE you can find a lot of material on Leetcode and similar sites (and of course books) but "Linux internals" has a near infinite depth.

I did a bunch of those panels in my time. Imo if you read 2-3 books on unix/linux/networking and can complete this wargame in a couple evenings you’ll stand out quite a bit.


NALSD question is a required part of the interview. https://sre.google/workbook/non-abstract-design/ I did a quick search and it looks like there are youtube videos explaining it so that might be helpful.

Other than that I was asked to implement a 'tail' command using my familiar language, and explain why deleting a file from disk doesn't free up the space.


> explain why deleting a file from disk doesn't free up the space.

Because System deletes only the “pointer” to the file and not the actual file. For the exact same reason, cut+paste is faster than copy+paste


It does delete the file, as long as no other processes are accessing it and there are no other hard links to it.


Please check this one (I know you can edit Recycle Bin settings on Windows to directly deleted the file, instead of sending it in there) -

I’m pretty sure Google is going to ask in the context of Linux, and isn’t referring to Windows or the Recycle Bin.


Why you said so? Google has teams supporting .net, sql server, Microsoft VMs as part of Google cloud offerings


In my experience the recruiters are great about helping you prep. They have a PDF called "Google Interview Prep Guide Site Reliability Engineer" that talks about SRE-SE vs. SRE-SWE vs. SWE, and links to books and topics to study.

Kirk McKusick's "FreeBSD Kernel Internals" course[1] was recommended to me, and it was excellent. But not cheap at $1495.
