If you had to choose

If those 3 were my only choice, I'd go with...........McDonalds.
Seriously though, since you're a student, I assume you're planning on going to the company school? In that case, it doesn't make much of a difference. Make your choice, get the training and your year experience, and then go to greener pastures.

 

Well, in that case, then it really comes down to personal choice. Which company offers more of what you want? Hometime, pay, tuition reimbursement, etc? Any of the 3 will give you experience, and that's the main thing you're looking for here....anything else that you can get is just icing on the cake, IMO. Each of the companies have their good and bad, so it's really up to you and what you want out of it.
I'd suggest getting a notebook and making a list of "demands" and do some research, and then see what company scores best.
