Okay, let’s tackle this. So Donghun Yun has 23 years of experience in HR, which is a significant amount. He has worked at two large companies, Samsung Electronics and Samsung Heavy Industries. His role as HR Director at Samsung Electronics suggests he has expertise in employee relations and HR consulting. Skills like technical recruiting, employee relations, and HR consulting are in demand in South Korea. However, considering his experience and industry, I would estimate his hourly rate to be around $120. This is lower than what I would expect for a similar role in the US, but taking into account the cost of living in South Korea, it seems reasonable. Some HR professionals with similar experience in South Korea might charge higher rates, but this is just an estimate.
