Oh what i meant was besides meeting the basic requirements stated, which is available on SIA's website or the papers. You definitely have to meet the basics, other than that, it;s all based on your character, personality, how you handle yourself and if you are an all-rounder. Your major in university or even your post in your previous job does not weigh much at all. Someone has posed this question to me about working experience and how important it is. It is important to a certain extent.
On another note, Knightwhosays_NI had fortified what I had said earlier. It's based on each individual and their preference. Some think long term, some think short term.
