I'm a freshman/sophomore at a target school working at a HF this summer. I want to know if I should start applying for IBD SA 2020. Morgan Stanley's and other firms' applications have already opened, but I am concerned about the IBD firm contacting my current/future employer (the HF) to verify employment and thus causing me to lose my 2019 offer from the HF should they think I'm already looking to move on. I just want to keep my summer 2020 options open. Should I wait to apply until I have already started this summer's work?
