Are you a career switcher or not? If you are brand new to tech, then you will benefit from a 2-year program so you can do an internship and get 2 shots at recruiting. If you are familiar with Tech, 1- year program is probably the most efficient and fastest way there. It is intense but tech recruiting tends to be much more immediate as opposed to consulting that can have a lead time of 6 or even 9 months after offer. Tech is usually a few months as the companies are not willing to wait a lot time and so you could recruit in the spring for the summer/fall start.
I am not familiar with the specifics of tech recruiting at these 3 schools but these general principles stand across the board.
P.S. You want to pay attention at the employment reports to see where in terms of geography people are recruiting. I assumed you were talking about EU in my reply. Then I looked at your username and wondering if you are in EU or not... if you are not from EU, there will be some considerations for a work permit which makes recruiting always less fun and more complex. Usually the rule of thumb is that you want to go to school in the country/continent you are going to recruit.
Yes, dual EU. Definitely want a program that has full internship. Thanks.
