I previously worked in a Big Four firm and performed well. Didn't end up well with the firm as I was promoted to a new role, where I worked for 2 months, then suddenly quit to join another firm. My boss was quite mad at that time.
Currently, I am considering applying to their strategy arm in another continent. However, I'm a bit concerned that my ex-boss will give me bad comments if there's a reference check, given that Big Four cooperates quite closely between different regions and Partners may know each other. Is this something that I should be concerned and stopping me to apply for this role?
Thanks!
