To all who inquire. If you are an insurance agent, then you work -- generally -- on a straight commission basis. Your expenses are your own and you are a 1099 for tax purposes.
If you are an unpaid Intern, as can be found with many types of companies, then the internship is regarded as a learning experience. Often you can use it for satisfying credit requirements of a particular college course. However, to say that this is an "HR internship," which implies a generalist support role, rather than a supporting role in just recruitment, is odd to me.
As for the company, it is very strong and among the largest and most highly rated financially in the country.
If you read any ad that says "unpaid internship," whether for a university,in nonprofit, in marketing, etc., it is just that. You'll do a lot of what used to call "grunt work." However, I do not understand why some have stated that they have expenses. Don't mix up the role of an intern with that of a contracted agent.
