As you can see, the program really focuses on leadership and entrepreneurship, with emphasis on the business aspect. The structure of the capstone project will be different for every major, but generally speaking you'll be with a team of 3-4 people, seeking to solve some industry problem. Every professor talked a little bit about the industry ties that they had; these teams can jump onto existing projects or if they have compelling projects that address some industry concern they can solve. In terms of resources, every research lab will put an effort to provide the resources needed for M.Eng students and their projects. I don't believe they would ever give funding to students but the existing resources are definitely there for the students to use.
What do you mean by the official admit? You were suppoed to get an email with the official acceptance and a link to accept or decline the offer. This is the official way the University deals with admits.
