你们有销售经验吗？experience dealing with people?

I was engineer. Somehow became sales after dot com bubble burst. Very different. Need to take rejection without hurt on feeling. We hired one retired sales women from a large company (in that industry) as a contractor. She started crying (she told me afterwards) after contacting one company many times without any positive feedback. 

milking type sale and hunting type sale very different. 

sales for Apple vs sales for unknown brand from China (with tariff and anti-China sentiment) very diferent.
