Frogmore Real Estate Partners interview questions

The interview started off very professional but towards the end quickly became inappropriate. I was asked whether I was married and had any children. After responding that i didn't, i was immediately asked to come in for final round interviews. All these questions came from one senior individual. It left a poor lasting impression. It seems like a typical 'old school' property company that is in desperate need of a HR team to train them in commonsensical do's and don'ts.
