Accenture Airoli and Vikhroli, Mumbai City, Maharashtra, 400081

Hi team,
My cid is c8375974.
I had appeared for interview on 29th nov 2019 and had been told that i cleared all the rounds on the same day. They also made me upload documents in a hurry.
Still yet i have not got offer letter.
The status on portal says "owing to businesd reasons we foresee a delay in processing your candidature".
I contacted talent coach many a times by send mail and calling i did not get any response.
Earlier in august 2019 they callef me for interview at their location and canceled.
I just want to say we also invest our time by taking leaves for interviews and uploading documents.
Atleast value it and respond to the candidate.
Didn't expect it such from a good company.
Too much disappointing experience.
