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.
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.
