I applied online on either Sunday or Monday. Got a call from the HR lady on Tuesday. Interview was Thursday. This was for the Times Square location.
There were 8 people there including myself. First we made name tags using an adjective that describes you. The adjective had to start with the same letter as your first name. So I suggest you go in knowing an adjective that you're going to use. We briefly introduced ourselves and explained why we picked that adjective.
After that, we were broken into 3 groups, and had to build a toy out of Legos. We also had to make up a company name, slogan, jingle, the name of the product, the age range, and a special feature. And I'm forgetting something else. We had twenty minutes to do all of this. Make sure that you are actively participating in the group, and that everyone gets a turn to present. It was a very relaxed and laid back environment. I am usually not the most talkative person in social situations, and if I was relaxed, you will be too.
Once everyone had presented, they had us pick an item that you brought with you, (could be anything - I picked Chapstick) and you had to try and sell it to them.
Out of eight people, seven got a 1:1 interview. One guy wore saggy jeans and a t-shirt and still got an interview. (I still don't recommend doing this.) I was first up, so I didn't have a lot of time to get super worked up and nervous. I think I did a lot worse on this part of the interview.
First an HR rep asked me some questions! briefly went outside, and then walked in another woman! head of a specific department. They said they thought I would be briefly suited for that position instead. The interview included questions like "tell me about yourself," "what would you do if this happened," "how long do you want to work here." I stumbled on some words, but I think I did a pretty good job answering their questions. She also gave me a job description and asked about my availability. The only part I didn't like was when the second woman asked me how old I am. I'm 17, but will be 18 in a week. She said, and I quote, "I wouldn't put you past two." Yes, I know I look young, but I definitely do not look two. 13, yeah. I thought that was a little rude of her. Anyway, she walked out and the first HR woman came in a minute afterwards. She told me that they will have to wait until I turn 18, then they can run a background check, and will call me once they do. I was offered the job.
Overall, the interview was very relaxed and informal. I wore black pants and a grey blouse.
