They send emails with a screening process of questions and answers about previous experience. Seems fair enough then, then I was asked for an in-person interview. Which it was very long but very interesting. You can tell they really put am effort to make a difference in the architecture discipline, but they dont seem too interested in your time, portfolio or experience. I had the sense they just want some hands on projects and production.. which seems fair but it's like, all the effort you put to show you are a different and special firm, it's thrown away by being not considerate with interns or respect of someone life. It shouldnt exist a trial unpaid period, you already know if someone is good for the position on the first interview. If you need hands on a project you pay for it. At least a symbolic stipend. Anyway, they dont force you to do anything, I went there bymyself as a grown adulto who was really motivated by the position, but the lack of appreciation and consideration from them it's really discouraging. As human qualities, everyone seem nice both in interview and in office, and it's clearly a place you can learn a lot from.
