If you can go to one of their Open Houses, do so. It will give you a great idea as to what the "research position" actually entails. The whole thing is about 2 hours. There will be a small presentation, a sit-in with an actual employee (you can observe how they work), and then you will have your interview.

Extremely lengthy. 4 stages over about 2 months. Panel interview that took 6 hours. One panelist did not show and added another interview stage. Due to length, I found a better offer and declined after finally getting to an offer.
