On Jobiki, we don't have job postings. Just companies and data about them. So the "minimum salary" and "developer" searches are more job related, while we are more company related. Either way, helpful feedback.

As for the "proper walls and a proper door" aspect, are there developer/traditional employee jobs in Europe that can have a real office? In the US, unless you are a manager, executive, very experienced employee, you don't usually get an actual office. Maybe its more common in Europe?
