This is the point where I usually end up walking away and making it known that the reason is due to the convoluted, time consuming process being a huge warning sign of things to come. A few other no-gos include being asked to fill out a skills matrix after phone calls and a clear visual representation of the info has already been shared, a resistance to an in-person right away to see if it's a good fit and the all too common coding assignment (this is what GitHub/portfolios are for).
Do these seem like miniscule issues to you? What are your own issues that get you to walk away as a freelancer/contractor?
