Technical Interview Practice with Java

Why practice technical interview problems with Java?

You’ll need to pass a technical interview if you want to be hired for a technical role. Don’t worry — these interviews are pretty predictable, and the same kinds of problems appear again and again. Even if you don’t have a technical interview scheduled just yet, practicing these common problems will help you grow as a programmer and problem solver, and will help you write cleaner and better code.
