Hi, 
 I have a interface from where i want to invoke process model having user input interface. I have used start process it invoked the process model but showing stuck in node having interface configured and noting is displayed in parent interface also. 
 However same process model is configured in Record action of record type design objects , it's working fine.

If you trigger a process from an interface using a!startProcess() the process will be started Asynchronously. The parent interface will continue to display and you won't be able to see the user input task from the process even though it is assigned to you. You need to follow different approach to achieve what you are trying to do.
