Pretty ridiculous interview. They wanted to do a web interview. I replied that my computer didn't have a microphone. They didn't bother responding, so I figured that was okay. I got on the interview and and my interviewer was all "What you don't have a microphone, I don't know what to do!" So I got on the phone. The interview focused on making diagrams and stuff. I'm not really good with all this Visio type stuff, so I didn't really get it. They asked how to implement the inheritance of a strongly typed language, like Java, in JavaScript. The answer involves calling the function that serves as the constructor of the super type in the constructor of the child type and then setting the prototype of the child type equal to the parent constructor. I tend not to remember all this stuff because frameworks like Backbone will do it for you, and also because JavaScript is duck-typed, so you can use the _.extend method from lodash or underscore. and if you don't rely on instanceof, you'd be fine.
