Your answer should show that you understand the importance of collaboration and communication in the workplace, as well as your own role in helping to make projects successful.
Answer Example: "I think the most important thing front-end developers can do to help the overall development process is to be aware of their surroundings. I’ve worked on projects where there were multiple front-end developers working on different aspects of the same website, but no one communicated with each other. This led to some issues down the line when we had to combine our work together. If I knew another developer was working on the same component as me, I would reach out and ask if they had any tips or tricks they could share. This helped us both create better work and ensured we weren’t duplicating any efforts."
This question can help the interviewer understand your experience level and how you work with other developers. If you’ve worked on projects alone, explain what those projects were and what your role was in them.
Answer Example: "I’ve worked on several projects as the sole front-end developer.
