Big companies value experience, while small companies value profit.

I think experience is more important. After staying in a big company for a few years, small companies can pick whatever they want after accumulating some experience, and the salary is relatively high.

Sales intern is a talkative profession with a lot of knowledge.

Sales make a lot of money, but there are fewer things that can be contacted, and they are still sold after a few years.

Don't look at immediate interests, look at the long term.
