Getting in is the most difficult part these days, at least that's what everybody is saying. Personally, I'd say the best way to get in is to be direct, to be yourself, to be prepared, and most of all to be persistent.
Be directIf you want to get in, find out if any game companies have offices nearby. Most developers / publishers have very informative websites that also tell you where you can find their offices. If you're not applying for a specific postion, (i.e. the company is currently not hiring) make it a priority to find out who works in the human ressources department of the company (companies) you wish to contact, and send any mail dealing with future employment to them directly. You'd be surprised how many resumes get sent in each day and are shredded right away. By sending it to their human ressources people, you'll have a good chance somebody at least reads your stuff.
Be yourselfWhen sending in your resume, try to make yourself look good
without making stuff up! This may seem obvious, but many people believe that they'll have a better chance if they are a little "creative" with their CV. Trust me, this is a bad idea all around. It's bad enough if they find out during your job interview, but it's even worse when you get away with it and then end up having a job that's completely over your head. Also, team skills are a huge plus. You'll want to be your most charming, self confident, and natural self. Don't be surprised if part of your job interview takes place at Pizza Hut. (mine did!)
Be preparedThere's tons of advice on what your resume and / or portfolio should look like - not surprisingly,
Blizzard and
Acclaim as well as
most other companies have submission guidelines online which give you a good idea of what they're looking for. There's a reason why these guidelines are there: On any given day, the big employers get sent an incredible amount of sub-par work. Reading these guidelines and sticking to them will make sure that you are not wasting anybody's time, and it'll also improve your chances drastically.
Also, what they don't tell you is that during your job interview, you'll be asked to talk about your work. It's a good idea to prepare a little speech about what you do, how you work, and most importantly, why you love doing this. Be prepared to receive a lot of flak. During my interview, they tried to poke as many holes as possible into my stuff, but I think I did a pretty good job at defending my work without sounding like a conceited jerk. Which is the most difficult part: Standing by your stuff while still being nice. My advice would be to simply practice this situation with a friend.
Another thing I find worth mentioning is:
DON'T WEAR A SUIT! Wear a presentable yet non-formal outfit - a nice button-up shirt, decent jeans (No stickers, patches, or torn knees), and some nice sneakers will do most of the time. It doesn't hurt if you ask them what you should wear.
Be persistentChances are, you won't find a job right away. There's always somebody who's more talented, more charming, more competent, or simply more reliable than you. But that's nothing to worry about, because it's nothing you can change. Luck plays a huge role in whether or not you can get in. In most cases, it's not your fault if somebody doesn't want you, it's rather that there's somebody else whom they prefer. But if you walk out of an interview and have a feeling that it didn't go too well: Sit down, take a deep breath, and think about why it didn't go well and how you could do better next time. Then have a coffee, and move on. Keeping yourself busy in between interviews is the best thing you can do, like for example what FXcalibur is doing. Also, I recommend reading whatever kind of industry-related books you can get your hands on. And most of all, play as many && much games as you can.
That's all I the advice I can give right now - gotta get back to packing my stuff up.
