Tell me about a time you influenced your team to adopt a new technology. How did you get buy-in?

When I joined Acme Co, our web application used jQuery and vanilla JavaScript. I wanted to introduce React to improve developer productivity and application performance. However, my team of 15 developers was comfortable staying with jQuery.

To gain buy-in, I researched the benefits of React and put together a presentation tailored for my more junior developers. I focused on how React would speed development and reduce bugs - things they cared about.

I also identified two engineers who were eager early adopters and asked them to build a prototype page in React. When they showed how much faster features could be built, it helped convince the skeptics.

Over the next quarter, I slowly ramped our team up on React through demos, documentation, and pairing new React code with jQuery. Within 6 months, we had completely migrated our application and improved our feature throughput by 20%. Focusing the case for React on tangible benefits for our specific team was key to driving adoption.
