People at New Relic Say

This information was sourced from reviews originally posted on Glassdoor.

Excellent grassroots programs with excellent people running the ERGs that can teach you a lot (just don’t expect the company to ever buy in)

This is truly a company of nerds. I should add, nerds WITHOUT inflated egos. It's apparent that everyone swarms together around a certain problem.

Great work life balance and culture here at New Relic. I have met many smart and wonderful people during my time here. I have grown my career here and learned a lot with a wonderful team.

Good benefits, still a well recognized name in the industry. The old guard of entrenched engineers are really smart, but don't expect their time or help. Lots of diversity and inclusion efforts, although there isn't any real diversity or inclusion at the company.
