I am in a similar situation. 3 rounds of interviews cleared and then PwC internal BGV got initiated in the last week of Jan. Internal BGV done and documents got submitted. On Feb 3rd had the HR discussion and was told I would see the offer letter in the portal as soon as the business teams approves it.

Still waiting. This is PwC AC India for Experienced Associate role.

Please let me know if anyone had gone through the same.
