If you've passed all the necessary rounds at Accenture company, like exams and technical interviews, and did well, you should hear from their HR team in the next few weeks, but sometimes it can take more than a month as it did for me.
So, when the HR contacts you, to get some documents that are to be submitted, make sure to provide those promptly and remember to follow up with them regularly to stay updated on your status. You can ask about when they plan to make a final offer. It's okay to say you're also considering other companies - they'll get it.
After you send in your documents and do well in the interview, it can take from a few weeks to a month to receive a formal job offer from Accenture. Their hiring process is slow. It took me about a week, but my friends waited up to a month. If you're applying for a job that's available right away, you might get an offer in about two weeks.
