We ask for something stupid like "3 years of Pascal experience." If the resume has it, it goes straight to the trash unless it has specific real-world Pascal experience.
I hope you are clearly marking this as "nice to have".
You'll also filter out people smart enough to know that this is a bullshit keyword matching game and the only way to win it is to put the keywords on their resume.
Because they assume that the job posting was written by a non-technical idiot, and 95% of the time, they'd be correct, and they are just playing the game as the game expects to be played.
Look. If you're looking for 100% integrity and honesty from everyone in their communication, you shouldn't expect find it in a corporation's hiring and HR process. Everyone white-lies (or black-lies) all the time, both up and down the chain. The bones of this interaction do not value, reward, or even want honesty.
I have Pascal experience :) My first job was a Delphi application...
For that time and task (accounting app), Pascal was great.
