Got the necessary clarifications and asked additional questions on the infrastructure. Gave the architecture, design, DB and service configurations. Exceptions and what to expect. Interviewer asked me to give the SOAP request of the services. I didn't work on those but asked follow up questions on what each role will do in the company. Interviewer said that if you answered the SOAP request then it would be Technical Program Manager and if not it would be Program manager and said that he doesn't have any opening for Program Manager and would inform the same to HR.
