Skanska interview questions

It was the most awkward interview in my 17 years of professional career. I was interviewed by one man, I am a woman. The first thing that came out of his mouth was "do you have any children", I responded how is that relevant to this position? He said, because we expect women to work as hard as men and women think they can just pop kids, work less hours, or work from home, if you think like that you are in the wrong place. My jaw dropped. I think I blushed. I was on shock for few seconds. I was not expecting that question ever. So I responded that "I am a hard worker and I think the women you are describing have previous arrangements with their managers" He did not mentioned anything about the project that I was interviewing for. Maybe the project managers are not trained to conduct proper interviews, or not trained at all.
