Step 2: about 2 weeks (1 week of hard core, 1 week "fluffy" studying)
Interviews: took off only December (4 weeks), but should have taken off January or part of January as well. But it's hard to anticipate when your interviews will fall...non-competitive fields have more flexible interview dates than competitive ones (where you might get only a couple dates to choose from). Ask around to find out which months your chosen field tends to interview in (i.e. early match specialties, peds, etc.)
