We visited in April '07. My employer wasn't hiring for my expertise at that time. So I had nothing to apply for. But a couple of months later they advertised. I applied, had 4 phone interviews, each about an hour long. got job offer. However, offer was processed in a far-less-then-timely manner (by someone who is no longer with the company) and so I did not get it in time to get a proper work visa before we left the US. We went on visitors visas, and I had - per advice from my employer - destroyed all evidence of a job offer as I would have been in deep, deep trouble if I'd entered as a tourist with a job offer! Applied for a work permit and got it 2 weeks later. After 1 day of perm employment, I submitted our EOI with 215 points.
The rest, as they say, is history.
