advice for someone almost 2 years out

I graduated in 2011 from an Ivy (see username), 3.8, 1500+ SATs, etc. I worked at MIT/Sloan for a year doing operations research, specifically startup strategy, helped a prof write case studies and develop a curriculum, and from there I went to work at a startup, developing its operational and marketing strategy. I've been doing that for 8 months, and - surprise! - it's starting to tank. It's a tough world out there.

I want to get into consulting now, specifically management or strategy (or geo-political strategy). I've never really had a go at this, save for one final round interview with BCG back in 2010, of which nothing came. I'm great with interviews and cases, perhaps shittier at networking. My question is:

How difficult is it to transition into consulting after ~1.7 years of relevant job experience? Ideally, I'd like to get into MBB, and I am willing to network/brownnose the shit out of countless leads to wrangle an interview - but 1) is this actually possible or likely, and 2) would they stick me into their incoming analyst class, or what? Is that conventional for a somewhat recent college grad? Or should I pack up and look elsewhere?
