Pros
I really enjoyed my time working at RTI. I was hired right after earning my bachelor's degree in Chemistry and it was a fantastic experience. I didn't have a lot of experience directly coming out of college, and they really took the time to train me and teach me new techniques. I got along very well with my coworkers and I am still in touch with a couple of them even today. One of my previous bosses even wrote a recommendation for me for a training grant I was applying for during graduate school. PTO (which includes sick time) is earned at a rate per month equivalent to 4 weeks/year and benefits started Day 1.
Cons
As a bachelor degree scientist, the opportunity to move to management was minimal (though that is understandable). The starting pay was lower than expected, though it is a non-profit.
