I have zero expectations from an intern. The scope of the programs vary wildly, but I have seen platforms that are as little as two months. It takes a month just to get someone a new laptop, access to systems, any kind of onboarding to processes, etc. Then you can give them a project, but unless they are exceptionally gifted, the mentor is going to have to spoon feed the requests. My experience dealing with people fresh out of school is that they need discrete assignments, there is less ownership and global thinking. The scope of the work has to be so limited that it requires minimal expertise.

Which is to say nothing of the value proposition of having experienced person taking hours out of their day to mentor someone with a limited shelf-life.
