>So why not learn it in a week then apply for the job?
For a lot of reasons. I'm not looking to work in compilers. OP sounds like the opposite of the type of people I want to work with. I enjoy what I work on quite a bit. I am paid well. I have the chance to build up the business and a team.
It is just an attitude that I see a lot. The candidate doesn't have XYZ specific knowledge. Find someone who is interested and motivated (e.g. someone who has independently taken an advanced course in a topic) and build them up.
I'm sorry that some candidate can't answer your trivia question, but if it could be taught in a 16 week course (~10 hours / week), you could find a way to convey it on the job (~40 hours / week) in a much shorter period of time.
For this scenario have new hires work through a series of designed problems. Have them implement and run into the pitfalls with LL, LR, and Packrat parsers. Show issues with left recursion, shift / reduce conflicts, space trade offs of Packrat, seriously whatever you want to demonstrate.
Even just write up a document explaining when to use each rather than bemoaning the lack of knowledge. Like how much cooler would the top comment in this thread have been if I had learnt something?
This feels a lot like "I want a candidate with the knowledge of a senior for the price of a recent grad".
