Scenario

TGB has decided to open a branch office in India. Candidates from India must provide an Aadhaar ID for identification purposes. Ensure that candidates located in India enter an Aadhaar ID that satisfies the following requirements:

  • The ID does not contain alphabetic or special characters.
  • The ID consists of three groups of four numbers, with a space separating each group of four.
  • The ID does not start with either a "0" or "1".

Configure the Candidate information layout on the Collect personal information step to display a field for the Aadhaar ID. Configure the form so that the field is displayed and is required only if the user provides the three-character country code for India (IND).

Note: For more information about the Aadhaar ID program, see https://en.wikipedia.org/wiki/Aadhaar.

The following table provides the credentials you need to complete the challenge.
