I am an idiot with next to no experience, and I may have fucked up in a huge way.
I'm in college and over winter break I interviewed at a hedge fund in chicago. I have a trash GPA (2.9) but I had my interview before the fall semesters grade were released. Knowing that 2.9 is a crap GPA, I didn't include it on my resume. As I should have expected though, it was the first question that they asked me (What's your GPA). I had a good semester and expected to raise my GPA, but I didn't check before my interview and I ended up screwing up on some of my finals and not really changing my GPA. Whenever the interviewer asked me the question, I answered with what I thought I would end up with, a 3.1.
I checked my grade afterwards and found that I did not really improve my GPA. I also got my offer from the hedge fund for a Summer analyst position.
The fund probably has 25-40 people, and I haven't begun the onboarding process, so I don't know if they will ask for my transcript. In short, I unintentionally lied in my interview. My question is what should I do?
