Can I enter at this point?

've recently quit my job and was invited to work on a startup with a friend in Asia. We raised over 100k in VC funding and were about to start but my partner had a family emergency and our investor pulled out because I can't do it alone for reasons I won't go into here.

After graduating from my target school (Duke) with a 3.6 in the hardest engineering at our school, I took a job as a consultant at a small software company that specializes in business software. My role involved traveling to big firms such as GS and KKR and implementing technical solutions that they request. However, I quickly got bored of the job and the people I was around and knew I wanted to leave 2 months in. I stayed for one year in order to keep my signing bonus.

Now, I'm faced with a dilemma. I've always respected the culture and ideas that flow through this website. I know that my aggressive personality belongs in finance and the reason I didn't go straight out of undergrad was because I wanted to do something different and was afraid of the long hours. Now, I'm more confident in myself and am having second thoughts but I'm no longer in undergrad and do not have OCR to help me land a job. I have plenty of friends in IBD and even some in PE but I'm not sure what type of industry I should enter. I interviewed at MBB in my last year but didn't land a single offer from any.

I'd like some advice to help me figure out my options and determine which roles are even feasible for me to enter at this point. I also hold a 750 GMAT so numbers wise, I think I am alright. I graduated in 2015 (last year). In terms of goals, I'd like to work in a high pace field and attend a top business school.

Thanks!!!
