The installation stops in the last screen "installation finished" and doesn't switch to the login-screen.
It won't "switch" to the login screen - the system will reboot if you have the command "reboot" in the kickstart file.
How can I configure the profile for users to answer all question that are asked after the first login.
The initial setup is called "firstboot" - you need both the firstboot package installed and "firstboot --enable" in the kickstart file.
All these things are documented in the RedHat kickstart reference at
