An Insider's view of OneMain Financial

What does career growth look like on your team?

We have a great progression path guiding engineers from being individual contributers up to management. I started as a software engineer and worked my way up through senior to lead. A key part to all of this was having 1-on-1's with my manager. These quick meetings helped give me clear direction and feedback to work towards progressing my career.
