How many projects is too many projects to single-handedly develop for a company as an intern?

This place I'm at fam! The fucktards won't even offer me a job, yet they're trying to put me on a 3rd & 4th system, after single-handedly delivering 2 projects already that met their expectations. A recommendation letter is great, but what I want/need is a fucking job!

You are there where they want you to be. Overloaded and in an extremly unstable situation.
The time you fuck up, you are the scape goat and fired.

Trying to get a positive from it, that is a lot of experience to put on a CV for someone who hasn't had a job. A lot of employers *are* decent people too - if I saw that resume, I'd want to give you a break, if you were up to the job. I can't stand people who take the piss like that.

Start applying for other things, don't think of yourself as 'intern level', that just a con so you won't ask for payment, and just try to imagine how good it'll feel to tell this lot that you're quitting without notice and going to a real job.
