Big 4 Assurance -> Top 10 MBA?

Hey everyone,

I recently started my full-time career at a Big 4 office in Boston and I am trying to figure out what my game-plan is now across the next 5 years. My dream positions would either be working for a venture capital firm that focuses on emerging tech, or an IBank division specifically geared towards M&A in the tech or energy sectors.

I graduated from Boston College's undergraduate Carroll School of Management with a dual emphasis in Finance and Accounting and a 3.56 GPA (major GPAs ~3.6 as well), and 150 semester credit hours. Due to the economic downturn, I ended up changing my initial plans after undergrad of attempting to acquire an analyst role at one of the IBanks that recruit at the school; instead, I took an offer given to me early in the 09-10 schoolyear from a Big 4 to work in their Assurance Tech market line starting Fall 10. I went with it at the time due to uncertainty about the economy and the better job security gained by a CPA license.

I am currently studying for the CPA exam and expect to complete it by the end of 2010. I have been assigned the Tech market line; I personally like tech companies quite a bit, but I potentially could change this over the years (i.e. switch to the Asset Management Assurance market team, or to Transaction Services for mergers and acquisitions due diligence) if necessary.

I now need to figure out what is the easiest way from my current situation to successfully get one of my dream jobs. My guess is that a top 10 MBA in Finance is probably the route to go. There doesn't seem to be much information out there for how auditors get into top MBA programs; my guess is that many auditors have to get a masters in accountancy to reach the 150 credit hour requirement of the CPA and don't have the time or money to then go for a top MBA. Fortunately, I completed the 150 semester credit hour requirement within undergrad.

My questions are:

1) Is a top 10 MBA the recommended route? Or would an MSF program make more sense for me considering my undergrad degree in Finance and Accounting? Or would applying within a year or two for a boutique IBank be best?

2) For the MBA, I think I would aim to first work for the Big 4 firm until I complete a busy season as a Senior Associate (~3.5 years into work). During those years, I'm thinking about doing a section of the CFA every summer (I hear CFA lvl 1 overlaps the CPA a lot). I would take the GMAT sometime next winter aiming for a 700 range score. Will I absolutely need to be in the higher end of the 700 range due to my background?

3) Would it be advised to move towards the Asset Management assurance line, or towards transaction services? Would I be better off auditing tech firms?

4) Is this route really that uncommon? Is it not normally successful? Do any of you know any former-Big 4 coworkers/students that did something similar?

All help would be much appreciated.
