Remember to include a mix of teamwork, leadership, and technical expertise within your response. Mature teams display expertise within their specific field, but they also demonstrate high-performance team dynamics. Also, do not describe strict adherence to any one development methodology as a sign of maturity. Facebook has a history of adopting flexible and fluid processes that are not aligned with named methodologies such as Scrum or SAFe.

"Maturity within engineering teams occurs across a number of key conceptual areas. These include teamwork, leadership, technical expertise, customer service, and agility.

Mature teams are able to demonstrate advanced team-focused operations. They know how to partner properly. They mentor and educate each other well. They are able to work through conflicts comfortably and support each other professionally and personally.

Mature teams have strong leaders, and all of the team members show leadership in their individual roles. They know how to facilitate discussions properly and allow everyone on the team to add value. They hold each other accountable and inspire the best in each other.

From a technical perspective, mature engineering teams have a wide variety of skill sets to lean upon. They are seasoned in the technologies that are most important to their products and they continually learn new concepts that add value. They are focused on the continual improvement of their automation and deployment practices. They have well-architected frameworks that support extensibility. Additionally, they are strategic and simultaneously able to execute tactical operations.

Mature engineering teams understand their customers. They are familiar with the personas they develop solutions for and they understand the value chain. They demonstrate user empathy and take pride in delivering solutions that achieve their customers' goals and improve their lives.

Finally, mature engineering teams demonstrate agility. They are able to roll with the constant rate of change within technology. They take advantage of new opportunities and handle the stress of unforeseen challenges with ease. They develop their solutions in a manner that aligns directly with the most important and valuable features. They deliver the right solutions in the right way at the right time."
