Even if that were the recruiter's intent, I don't think it's that clear. At no point in the conversation does the recruiter ever make an explicit request to have a resume with both of those on it. You might think there is an implied request from the recruiter for that, but I do not, and neither, it seems, did Stanley.
The only point in the exchange that I can see where the recruiter requests a change to the resume is here:
> […] we require having Unix experience. If you have it, could you update your resume and resend?
Which he does.
You'd rather higher a liar and someone that will follow instructions to the letter, even when they're incorrect?
It sounds like you'd hire this useless recruiter.
How many tens of thousands of university kids go through the hiring pipeline at Facebook each semester?
When you are doing things at that scale, you need well-defined processes. The process here was we need you to put exactly what this position requires on your resume, probably because the resume needed to be OKd by some keyword-checking system.
The candidate either was incapable of or refused to follow the process. Therefore, no hire.
The recruiter does appear to be a little clueless with the terminology, but there could be several reasons for this. Oftentimes resumes are input into an automated system that searches for very specific keywords, or the resume might be going to an executive who is very specific about what they are looking for.
At the end of the day, the recruiter gave very clear instructions on what to do. If Stanley had just followed those instructions and re-sent his resume, he'd probably be fine. Instead, he chose to be snarky and condescending in his response. The recruiter was very professional and STILL gave him a chance to fix his resume and re-send, but he still didn't.
Clear no hire.
Clear no hire.
