Okay, let’s tackle this. So Yan has 4+ years of experience as Sales Director, which is a mid-level to senior role. His location is the Greater Bern Area, which is a relatively affluent region in Switzerland. Mechanical engineering background adds some value, but it's not a high-demand skill in sales. Salary benchmarks for Sales Directors in Switzerland suggest a range of $80,000-$120,000 per year. Considering the experience and location, I'll estimate an hourly rate of $100, which is on the lower end of the range. However, this is a conservative estimate, and Yan may be able to command a higher rate depending on his performance and the company's budget.
