"I learned a lot from my employer but realized there wasn't enough growth opportunity to reach my goals. The company I'm working for is downsizing and allowed me to fill another role at the company. Unfortunately for both of us, it isn't aligned with my career goals. I'm grateful for the experience and what I learned along the way, but I decided I wanted to move my career forward, and I couldn't do that in that position. Although they're sad to see me go, I do this with my current employer's blessing, which is great because I forged a lot of great relationships there, and I've always been the type to build bridges rather than burn them."
