TBH, aeons ago, we had this as a high-pass filter (doesn't notice a glaring SQL injection hole, no problem with eval() on user input? Nope.) and a conversation starter (-why are you constructing a database handle right in the middle of business logic? -indeed; how would you do this?)
It very much depends on the code - but I was genuinely surprised how many applicants, claiming to be fluent and applying for a senior developer position, had problems just grokking what the code did (a while loop reading from database).
