Need advice on risky transition
I interviewed with a top bank in my region last year for a junior IB role and successfully got through 3 rounds prior to it be stalled due to COVID (interviewed with head of the group, 2 directors, and 2 analysts). One of the directors left the bank and offered me a role to join their start-up with attractive pay, learning opportunities, etc. I ended up joining the start-up since there was no indication of when the hiring freeze would end for the bank and I had already been waiting >1 year due to COVID.
Its been <1 year now and the start-up opportunity has been great, but I realised I still rather work at the bank where I can develop a better network, have established training programs, brand credibility, etc. I am thinking of reaching out to one of the Directors I interviewed with and inquiring about reapplying since I know that several others from that bank will be leaving soon once bonuses are paid out.
Any advice on what to say in an email with this Director? I should also note that it is risky for me to reach out as the people I work with now are all ex-employees of that bank and 1 of them (who brought me onboard this start-up) was in charge of their recruitment program.
