Vantaggi
The engineers at Qualtrics are smart. I can only speak to the Provo location, but I had a very good experience overall. Many of the people I met either came from the Valley to be near family or would have been good engineers in the Valley had they been located there instead.
Svantaggi
As an out-of-towner there was a bit of culture shock living in Provo, and I found the office to be the only place where I didn't feel out of place. I also got the impression that some of the engineers there would have liked to move around the company more – that is, switch teams every year or two to get exposure to different technologies and mix things up. Also, the office is full of junk food. I ended up bringing my own food because everything was so sugary.
