Vantaggi
First, to say that Mitratech doesn't care about its employees is absolutely ridiculous. Mitratech does so much to make sure their employees have a good work/life balance (open PTO, happy hours, early release, departmental outings, etc.). If you don't take time off, that's your prerogative and yours alone. Yes you work hard here but that's the point. If you were anywhere else, you'd be just another cog in the wheel. Here you get the opportunity to take charge of projects, make lasting changes, and hone your skills....even as an entry level employee. It's easy to move between jobs and it's easy to get promoted. You just have to put in the effort. If all you're doing is "just getting by" don't expect much.
Svantaggi
While I think that paying 100k to a software engineer right out of college is absurd (Mitratech isn't Google), I do think salaries should be higher. Your top talent will leave.
