Thanks for the quick response and clarifications. Experience with Linux and other UNIX-like operating systems is largely transferrable thanks to the standardization that resulted from the POSIX specification. As a result, the terms "POSIX" and "UNIX-like" by-and-large refer to the same thing.
My experiences are in particular with developing software for Linux platforms, which are the most popular of the UNIX-like operating systems. I also have experience using POSIX-specified APIs to ensure consistency and portability. Beyond software developers who have programmed in the 1970s, most people do not have experience with a true UNIX OS, and I would find it hard to believe that such outdated technologies are underpinning Facebook's advanced innovations.
I've updated my resume to indicate my familiarity with Linux, POSIX, and UNIX-like systems. Please let me know if there is anything else you need.
Thanks for your time and consideration, Stanley Zhang.

Hi Stanley,
Thank you for the tutorial. We're looking for experience working on Linux and Unix.
If you do not meet the above, please let me know if there are other roles you'd like to rank.
Best, ________
I'd love to see you defend why the guy who wrote the first half is bad at technical communication and needs to develop a professional attitude, and the recruiter -- who copies and pastes the same incorrect response over and over, showing no indication that they read a single word -- is a professional communicator with a good attitude.
