This may not be the usual interview story. It started back then when I was close to finishing with my degree. I got a phone call from, someone who knew my accademic advisor, pretty much asking me "can you do this next month?" and then "what is your ideal job" . This landed me back to back internships. So, when the "full time job" interview came I was already working there for about 9 months. Althugh it was more of a formality, I did get asked tough questions related to my field during a 1:1 interview. While I was an intern, there were also a few presentations for the whole group; I'd say those were part of the interview as well.
