HSBC Client Integration interview questions

I applied online and was contacted by the recruitment department about a month later. I went for the interview, which was competency based, and was asked the usual "tell us about a time you were in this situation" questions. After 3 or so questions the manager stopped asking questions and started asking me personal questions and asked why I wanted this role and why I left my previous employer (I immigrated). 2 months later I received a generic email from HSBC informing me that I was unsuccessful in my application, with no further feedback or comments.
