Imposter Syndrome

You're certainly not the first person to have Imposter Syndrome as college wraps up and you head into your upper-level finance courses. Even after taking the courses, not everyone is a Master of Finance and perfectly polished. You got the SA role because the interviewing team went through all of the candidates and thought you had potential and competency to learn and grow. No one ever expects analysts to be a finished product and a lot of banks will teach on the job about finance in general and more specifically about your role. Throughout my career I have interacted with analysts that were Ivy League and those that went to no-name public colleges and the common theme is that most of them don't really know what they're doing anyways. Spend the next few years (FT analyst years included) and learn as much as you can while minimizing making the same mistakes more than once. You're young and have already accomplished a lot if you've gotten an IB SA position, you don't need to have everything figured out right now. Good luck as a SA and just try your best, that's all you can really do.
