If You Want a Job at FAAGM, Which Programming Language Should You Learn?

Too Long; Didn't Read

The short answer is, don’t worry about the programming language. Any company (but particularly a large one) that is hung up that you know language X, but not language Y is a company for which you don’t want to work. Seriously, because it means that company is staffed by people who think that languages are really important to whether you are a competent. Languages are a tool, like a saw. Whether the saw is manual, table or laser is less relevant than understanding the basic principles of wood and how cutting it happens. There are plenty of people who know Java and are terrible engineers, it isn’t relevant knowledge to test.
