Industry Business Analyst vs IT Consulting for B-school

I am a senior at a non-target school, and graduate in May. I had offers from several 2nd-3rd tier consulting firms (Accenture, Deloitte, KPMG Management Consulting, PwC Risk Advisory, Hitachi), and then the industry firm I intern for. I took this internship because I had the opportunity to manage the implementation of a new SAP module, and thought it would be golden experience for IT consulting. While at my internship (happens to be at the Corporate HQ for a midcap company), I started to learn from the CIO of the company, and build a mentor-mentee based friendship. I was dead set on consulting, and he reached out to some people at some firms here knew (ended up getting an offer this way), and then ended up offering a position to me as a business analyst at the company in operations, and I took it (beat all my consulting offers, plus continue learning from him).

The group of business analysts are super aggressive in tackling problems, and will reach out to help business units increase efficiency before the problem is ever brought up to IT (where we are organized in the company), but I want to make sure I am going to be on the same level as other grads that took positions in these consulting firms. The experience is broad, but what do I need to do to ensure I stay competitive? I know the company doesn't have the brand weight of a strong consulting firm, but are there ways to leverage this experience to get into a top 25 bschool still?
