Dear Team Kritharth, the question to the interviewee is why did you choose HR and not what is the importance of HR. Your reply is more for the latter than the former.
As far as depreciation of assets is concerned, human resources also depreciate. Otherwise, the concept of retirement would not have been there.
Your argument that humans bring creative and intelligent solutions to stay competitive is absolutely valid. Nevertheless, the other side of the argument is that it is humans that deprive value from other humans. When managers demotivate juniors directly or indirectly, they reduce the value of other humans. This does not happen in the case of other assets.
For Asima
You have worked in a real estate company as an operations manager. Therefore, you understand the intricacies of operations better. You can utilize this knowledge in recruitment, training, and other employee development activities. You have an edge over other HR professionals. Your weakness could be that you may not know the "personnel" side of HR, i.e., knowledge of labor laws. You can supplement it with hardcore operations knowledge.
Thanks,
Dinesh Divekar
