Yup I got my job with family connections, my mum and brother both work for the NAB.
I got it straight out of high school because it also suited them to put me on. Im deffered this year, so I could sorta work whenever, without having to study or anything.
I used to work only two days a week at the branch in town, but then it got increased to four days at another branch. I started as a Temp, which is like bottom bottom rung, but you get paid a lot - almost $25 a hour, but its no guaranteed work. I used to get rung up at 9.20 (The banks open at 9.30) and have to rush into work.
Now im happy with my four days, but there is heaps of competition for positions, especially entry level ones. Ill be looking to transfer my work to Melbourne which will be quite easy, because once you are trained its easy to find work, but there is a lot to know and learn in the first few months. Lots of time and money gets invested into putting new people one, I guess like any job, but its fairly crucial to get it right.
Hope this helps.
