your experience is next to nothing (you cannot really consider 1 year as an experience); you are female, while your type of job is more suitable for men, and competition is extremely high in this field; you have a little kid, so your steady attendance at work is in question. That's in case you even don't get any invitations for the interview.
If you still do get the interviews and later aren't selected, it has to do something with your appearance, personality and presenting yourself.
yeah.. and your nationality.. maybe the Company simply doesn;t have a quota for your nationality, unless you are under your husband's sponsorship, then not all the companies like to hire the employees on family visas, as it's a headache to get a work permit for them..
