Here's my guide to the interview. I'm presenting this from a more professional perspective but anybody else who works on the executive or even middle management level will probably agree with me.
First and foremost you must always remain positive with an emphasis on progress. Most employers are looking for employees who are willing to grow with the company. If you create the perception that their company is just a stop on your journey then don't expect to get the job.
Disneyland has a very high turnover rate for this very reason (and the lack of hours, low wages, etc) and they do want to prevent that as much as possible.
Do not focus on your shortcomings and don't allow whoever is interviewing you to do so either. They're making sure you can handle working there and you need to prove that you can handle working ANYwhere.
Aside from that there are a few minor pointers for Disney specific applicants.
Enthusiasm
Appearance
Competence
I put these in this order for a reason.
Enthusiasm is paramount. Think of it almost as an audition. Don't over do it though. If you're too bubbly and obnoxious you're not going to get the job. Be as pleasant and happy as you would like a Disneyland employee to be towards you.
Appearance is also very important. Disney does have a code for appearances. Nothing too over the top. Small earrings and light makeup if you're a lady. Be clean and well groomed of course. Obnoxious hair color or high lights will hurt your chances as well. They don't want to an environment where people are trying to be noticed for their uniqueness sad to say.
Competence is very important as well. You don't need to be well read but you do need to communicate in a manner that everybody can understand. Speak slowly and communicate clearly. Record yourself speaking then play it back and see if you sound like an idiot. I'm dead serious.
I noticed that there is a young lady making a move to Orange County to apparently make it and would like to work at Disneyland. You'll notice a lot of people trying to shoot you down. I'll try to be a little more constructive.
Housing
1. It's very expensive to live in one of the safer areas of Orange County. Expect rent for a two bedroom apartment to hover around $1500/month in one of the less affluent neighborhoods. If you're looking for something in an area with less crime you're looking at about $2000/month. Make sure you get a place with utilities paid.
Transportation
2. Driving in the state of California can be costly. You must have insurance and gas is expensive. I recommend finding a hole in the wall insurance outfit that will sell you liability (all that is legally required) which will keep you safe if somebody else hits you or you hit somebody. You may not be able to get your car fixed if it's your fault but at least you'll be covered for any damage to the other party. Make sure you get an economical vehicle that is easy to maintain. You cannot register your vehicle without proof of insurance.
Other Bills
3. You'll likely want a phone and you may need to eat and wash your hair and other things like that. Be sure to figure these into your budget.
Education
4. Get your butt into school. You can defer your college loans until you graduate which makes it easier and interest rates are very low for most loans. You don't need to go to UCLA to get a good education so don't worry about going broke after you graduate. If you are going to do something like writing or acting, you better have some training unless you're incredible. I want to emphasize
incredible. Many aspiring writer and actors got where they are using contacts they've made while learning their craft. Your talent will only get you so far. If you want to be writer don't even think about finding a job without somebody backing you up. It helps to have an educator you can reference.
Showbiz
5. If you seriously want to get into the industry be prepared to pound the pavement. Living in Orange County is a little difficult because you won't exactly be in the heart of it all. If you plan on acting you will need to spend a great deal of your days going to audition after audition. Disneyland will not get you the exposure you may be looking for. Remember that you're not part of a minority. There are a lot of people looking to make it big in showbiz. If you don't have a backup plan you may find yourself heading home before you even got started.
I wanted more than anything to become an actor after I graduated high school. I decided that I didn't want to go to college and instead started going to auditions. I learned very fast that it's a big world and that I wasn't as special as I thought it was. It was a reality check I wasn't expecting. After just a month of failed auditions I found myself discouraged. I met 8 guys at my first reading for a Coca Cola commercial who could have been my twin. The only difference was that they had been doing it for years and were substantially better than I was. I gave up, got a full time office job, and eventually went to tech school and did what I should have done after I graduated. I can't help but think I'm a few years behind where I should be in the world. I have a good job now and I make decent money. Heed everybody's advice. You're planning a trip to nowhere if you don't wise up.
I don't want to rain on your parade but you need to be serious about this.
