Tl;Dr
As an intern, if your recommendations are being ignored should you try a different approach or give up? If yes, what is the best approach?
Context
I'm an intern for the summer in a small high-tech business. It's my second internship with them and I have been given a complete project to manage and realize despite my lack of experience; therefore I know they do trust my judgment and professionalism.
The thing is, I feel like I'm not taken seriously during discussions and my recommendations for the business are being ignored. Given that I'm leaving at the end of the summer should I:
- Push harder as I know some of their practices are bad and cost them lots of time and money
- Try to reserve some time at the end of the summer to write down everything I observed and give a copy to the relevant people (whether they read it or not)
- Mind my own business and just do my best - I tried, it's their problem now
- Instead of talking about technical merits with the other engineers go to the bigger boss and switch to money talk on how these practices are costing him.
