Front end technical interview questions

I'm not sure if it's required or would keep you from landing an entry level job but I would definitely familiarize yourself. The more you know the better. What's more important I think is understanding JavaScript as much as you can. If you can show them you actual understand the language and how it works, they will probably think you can pick up on other stuff as well. Other common things I see, even from the company I currently work for is whiteboarding, and debugging JavaScript.

Whiteboarding can be very frightening and I have never actually done it myself, but handwriting code spouted at you when a few people are watching you can be nerve wracking and I think it's a good idea to practice that so even if you r nervous you can still perform.

Then debugging comes back to showing you understand the language. We currently have a part of the dev test here that is just debugging a function, without using a computer. You should get comfortable looking through code and finding things that stick out and don't look right.
