People at Nvidia Say

This information was sourced from reviews originally posted on Glassdoor.

They treat me better than anyone when it comes to compensation. They took a look at how long I was in industry and what I was doing and paid me the going rate for those numbers. They didn't consider what I was making now nor any of my other offers. That made the Nvidia offer 50% higher than my current job and all other offers.

The people are really exceptional. People care about their work and collaborate well. The philosophies that were noted on my way in the door have proven to be how the company operates. It’s not lip service.
