Optra Health interview questions

I have applied for the post and got a call from HR. I told her that I have a kid and due to that I have a break in my carrier for two and half year. After hearing me, she scheduled for an interview. I reached before the scheduled time. I was sent to HR for light talk . During that talk she again asked me, "Do you have kids?". To that I have replied "yes". Her reply was ,"We are sorry. You are not fit for this job." The interview never happened. Before the interview I got rejected because I have a kid.
