NALSD question is a required part of the interview. https://sre.google/workbook/non-abstract-design/ 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) - https://www.lacie.com/support/kb/available-disk-space-does-not-increase-after-deleting-files-006369en/#:~:text=Available%20disk%20spaces%20does%20not,located%20in%20each%20hard%20drive https://www.lacie.com/support/kb/available-disk-space-does-n....

      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
