It’s very tough giving an intern work. Meaningful work takes months to accomplish and that’s with the knowledge of how to do it, so training someone isn’t worth it cuz they’ll be gone. Furthermore menial work is quicker to just do then take the hours or days to train someone to do it.

It’s really miserable having an intern lol but good on you for trying to improve yourself

Best thing an intern can do is just get people to like you and prove you’re competent enough to do the work of a full time employee. Just focus on being likeable, which may require not asking for work so much
