How to resume an Anonymous Intelligent Advisor Interview midway

Summary:

We have a requirement where an interview starts as anonymous, and in the mid way we trigger login. Once logged in, the user should be able to resume the same interview.

Content :

The requirement needs us to let users to start an application as anonymous users, then reach to a screen which will trigger our SSO login allowing user to login midway of application and then resume with the rest of the application. The entire Application is one single interview.

We have been trying to do the same and manged to reach till the SSO login and on redirection, user is logged in but the Application form resets back to stage 0. Here we need to retain the old user data and resume from where we have redirected for SSO Log in.
