RE>MBA>Boutique HF intern>Automotive Strategy & Ops.. Now what?

Hey all, Been thinking of joining the forum for years, today finally decided to dive in.

So my story is: I worked with a mid-size Real Estate Investment and Development opportunistic firm for 6 years and moved up quickly to a VP position in 6 years. The fact the firm was family owned had a glass ceiling and therefore I decided to look for other opportunities. MBA was one of the options and when I got a call from one of the top B-schools (think top consulting target school - Majored in finance). I took it on hoping to take the time to figure out what and where next. But i was really clear I wanted to join PE, HF or AM/ER. Fortunately I was able to land a boutique hedge fund internship focusing on Equity Research in Singapore, which I really enjoyed but they weren't looking to hire anybody full-time so that ended without an offer, but made some good contacts (still in touch with my manager).

Post MBA I continued to look for work and started to get a little desperate and started applying for jobs I wasn't sure I even wanted. 5 months after graduation, I landed a couple of offers in Corporate and decided to join one of the major Auto companies in a regional office working in a Strategy & Operations role. I enjoyed the role for a few months till I was learning about the industry and understanding what the role is about. Having worked in smaller one-office firm/fund it was exciting/enlightening to learn about how larger corporate works, challenges that are faced in terms of strategy development and execution when working with multiple regions.

Its been almost a year since I joined here and now each day I feel I made a massive mistake settling for something I dont give a toot about!

Now, knowing where I am. What do you think I can do to move back into the target industry? Anyone else here who has successfully moved into PE/HF/AM/ER after a corporate stint. Any thing I can do to increase my chances? Wouldn't mind a transitionary step either.

Any advice?
