the actual writing usually takes me about 2 hours+1-2 hours for revisions a coupple days later for each essay. I usually take a while to think about how to write the difficult question for each one though. I had everything but the constructive criticism essay written for Tuck for about 3 weeks, then I had a light go on in my head and was done in about an hour.
Strange that people are having such difficult interviews at Tuck, as has been mentioned it seems counter to their culture. I wonder if they fear being overrun by wall street guys who aren't Tuckish so are being extra hard on people.
I had my interview for EA back in September and it was basically a continuation, minus the beers, of the conversations I had in the canoe club two nights before. straight run through of resume, why tuck, tell me about your teamwork experiences, I see that you play hockey...etc. we talked for a while about his internship, how it was effecting his career plans coming back for his second year and then he asked if there was anything we hadn't touched on that I'd like him to know and we talked about that for a bit.
The only "hard" question he asked me was if, in retrospect, I would have stayed in high school longer. I'd never really thought of that so I took a minute to think and told him that that wasn't really a realistic option for me so I was glad I left when I did but I still was under prepared for college and that was that.
