Best programming for jobs

I know many different programming languages. How do Best programming for jobs choose which one to use during my interview? Don’t get me wrong—I advocate learning and writing code in many programming languages.

But when it comes time for programming interview preparation, I feel it’s important to choose one language to focus your prep on and get to know it very well. While many interviewers don’t mind you writing pseudocode during the early planning step of answering a question, others I’ve come across really want you to show you can write compilable code without an IDE.

If you’re going with Java, for example, and applying to Amazon, where Java is heavily used, consider reading through some of the best practices material.
