> Recruiter: We're looking for students with experience work on Linux and Unix
> Stanley: I have experience working on Linux and UNIX
> Recruiter: Your email and resume say Unix-like, which is not exactly UNIX.
The recruiter, by the end of this exchange has been given the explanation of why "UNIX-like" is the correct term, why it is being used, and why it is relevant. Stanley has also tried to take a more layman-like approach, and backed off the technical jargon to state "yes, I have that", using the exact terms that the recruiter used, despite them being incorrect.
The recruiter's last email contains things that are incorrect, and the response from the recruiter is irrational.
