Post-MBA FT Associate Signing Bonus Payout Date?

Interned summer of 2018, secured the FT offer, and begin training for a BB in July 2019. Searching previous threads yielded mostly analyst signing bonuses with little data on FT associates. Trying to plan out expenses for the next few months, and I was wondering if anyone had any insight with respect to signing bonus payout date. I know some firms payout in Q4 of the prior year (ours specifically does not). Was told by the A1s this summer that theirs hit in March of their start year, but so far no word from HR about it. Praying to god it isn't in the first paycheck with moving expenses, deposit/first months rent on a new apartment, and all the other post-business school overhead on the horizon.
