At least half of these questions are terrible imo, you want to know if people can program and if they can tell you when to use a String vs a StringBuilder, you wouldn't want them to memorize the docs. More on reddit.com

What, the, f**k.... While I actually do know the answer all of those, I'm dumbfound on why the heck you'd want to ask an interviewee any of those!

Why Map interface does not extend java.util.Collection?

... There's a positive correlation between begin a great developer and memorising those interfaces. Really. Believe me.

What is rehashing? When is it done?

Unimportant what so ever to every single job ever. And before someone goes into saying "yes, but you can implement an LRU cache precisely because of this behaviour" I'd tell him "right. You can also use a double-linked list."

Every single time I see those posts I just don't get it. Whom ever wrote this, reconsider what you want. Good developers, or someone who can answer trick questions.
