You should also have a decent reason why you want the MBA, and some sense of what you might do afterward. In my case, I had been through the dotcom bubble of 1997-2001 as a web developer, saw that all these companies had business models that made no sense, but didn't know what the better way was, so I thought I needed to get that MBA (in 2002-2004) to understand what makes a good business model.
I suspect if you read HN, you have at least a little bit of interest in entrepreneurship, and that could be what you talk about in your interviews. Don't worry!
Still, hard to say 100% without knowing your background and goals.
Now, if you're targeting a top-10 program, understand that for those schools it's all about the rankings. MBA programs are ranked on things like GMAT scores but also on starting salaries after graduation. What's the best indicator you'll get a high salary after graduation? Answer: you have a high salary before entering the program. If you want to get into a Harvard or Wharton MBA, tell them about your job making six figures at a Fortune 50 company and that you want the MBA so you can get promoted to the next rank of management. Acing the GMAT would also help. No matter what the brochure says, they don't really want dreamers who want to change the world. For those top-10 schools, the full time MBA program is really kind of a showcase to keep them up in the rankings. Then they can cash in with undergraduate tuition, executive and part-time MBA programs (companies usually pay for these for their employees), publishing, and other side ventures.
For this very reason, I had planned to work on my startup more and leverage it for getting admits from top 10 post exit.
