This subject came up in another thread.
I have never said that I had children in an interview - I had a 4 month maternity gap which I just left as that - a gap - when I applied for a job after having dd.
When I had been at that job a few months I applied to go on the company's training scheme - I still didn't say I had a baby because I was afraid that they would disregard my application if they knew I had a 9 month old baby.
I have moved jobs a lot and have never mentioned being a mother in interviews. I have always mentioned being a mother casually several months in.
That said - I have always worked in a very male-dominated environment, I know that I would have been unofficially written off if I said I wsas a mother. Has anyone else spent their career doing that?
Also, someone said on the other thread that they always take their wedding and engagement rings off at job interviews as well, I have never done that (am not married and only been engaged a couple of years so it has never came up as an issue).
It's very sad, but I know it has been necessary in my own case.
