I completely agree with the blog post writer. I have a job, and if I was to work on some other companies code base while still working for the current one, all kinds of copyright issues ensue (Swiss). Having someone, who is not an employee mess around in your codebase before they are hired is a lawsuit waiting to happen. Not worth it, and if you could convince me to come into your office for an interview and this is what awaits me I am leaving in no time. What happens if you don't hire the guy and sell a 100,000 copies with his work product in there? Do you own the copyrights or have a license to it? Probably not, and if it was me coding then my lawyer would have a field day with you and your company. So besides the insanity of not hiring a developer like you hire anyone else by references, reputation and limited work sample tests. Do you think you can tell some lawyer, please work on this case for 8 hours and then I will tell you if you get hired is going to go along with this? He will bill you 4000 chf for the pleasure and so would I. In Europe you have probation periods, i.e. you hire someone and find out that they can't do the work you terminate them on the spot. Is that expensive, relatively yes. But if that happens you already screwed up weeks earlier and it is time to pay the piper. This entire consult to hire, or whole day interviews just seems unacceptably unproductive and ethically as well as legally questionable.
