Accenture Senior Software Engineer interview questions

Very bad experience with Accenture HRs and recruitment process. I was interviewed for Machine Learning for Mumbai location. 1st round: telephonic screening. 2nd round: detailed technical round (also telephonic) The interviewer was good. Cleared both rounds and HR told that, you will get call from HR for Offer discussion. In the mean time submit all the documents required for further processing. So, I uploaded all required documents. Documents:- last 3 months salary slips, increment letter, pan card, aadhar card, DL, Degree certificate, 10th and 12 certificate, detailed BGV like form(where you have to provide all the personal information. like current address, permanent address, current employee ID, your manager name and contact and many more.) After they collected all this data, they simply sent me an email saying "There is no open positions that match my profile". The HR at Mumbai location didn't pick up my calls. So, I called Bangalore HR. She told me that, the offer has been given to someone else. Be aware of Accenture's recruitment. They simply collect all personal information and even after you clear all the rounds, there will be no sign of offer.
