I am a selected candidate in wipro wilp talent hunt-2020 process on 28th january. I accepted the offer letter and has been asked by wipro on 29rd feb to upload my documents. But there is no tab/option in my portal to upload the documents for bgv. I have been sending mails to manager. Manager. [protected]@wipro.com verification. Campus. [protected]@wipro.com. I have also tried reaching all the toll free numbers but there is no positive response.
The last date to upload the documents is 23rd february. There is a offer tab, joining tab, boarding pass tab but there is no documents clarification or document uploading tab in the portal.
Kindly help regarding this matter at the earliest possible.
