I haven't gotten job offers yet, but I got 3 on site job interviews at 3 big companies using the traditional hiring system.

However, I don't think it's unfair if you make use of your professional network. I'm pretty sure you spend a lot of time building strong professionals relationships at they have to pay off some way or another, so don't feel bad if you get an interview if one of your acquaintances help you to get your resumé noticed.
