Cognizant Technology Solutions — Not able to login on https://onecognizantbcazrapps.cognizant.com to complete pre joining process

Address: Jalgaon

I have been shortlisted in Cognizant for further validation process but I didn't get any credential from cognizant to login. Even when I tried to sign in through Microsoft account, I'm not able to log in on the One C portal (https://onecognizantbcazrapps.cognizant.com). The below troubleshoot problem was triggered. Kindly look into this, and help me out to complete my BGV successfully.

Message: AADSTS90072: User account '[protected]@gmail.com' from identity provider 'live.com' does not exist in tenant 'Cognizant' and cannot access the application 'https://onecognizant.cognizant.com'(onecognizant.cognizant.com_SAML_AzureAD) in that tenant. The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account
