I want to know when I can expect the offer letter from AML rightsource after being selected for associate analyst 2 role?

How many days it takes for the process and to release the letter?

In how many days does Manhattan Associates release offer letter?

I gave an interview in CITCO for operational analytics role and loan processing role. HR informed me I got selected and offer letter will be sent in a week and joining will be around August 14. But still no communication received from HR...
