I can see an inefficient company with a bad manager that doesn't really know what they want spending a year's salary in a bad process where they're continuously changing requirements, meeting in committees, inventing new rounds of interviews, etc. What throws me is the claim that this is possibly around the average. There are efficient companies out that there that can pick through the resumes in a few hours, arrange a few interviews, and have somebody hired in a week or two. So if there are efficient companies out there dragging down the average to a year, does that mean there outliers out there that are spending 2 years, 3 years , or more worth of salary to fill a position?
