This question checks two things: whether your goals fit what the company can offer, and whether you are likely to stay. A good answer shows ambition that grows inside this role and company.
"In five years I'd like to be the person my team relies on for a core part of the product, having worked across a few projects, earned a cloud certification and started mentoring new joiners. Your graduate programme and rotation model is a big reason I applied."
"I see myself as a senior engineer or tech lead, owning the design of a major service end to end and helping newer developers grow. I'd like that to happen here, because the scale of your platform is what I want to learn on."
"I'd like to be leading a larger function, having built a team with strong hiring and coaching practices, and contributing to strategy beyond my own area."
You can, but keep it realistic for five years (for example, senior engineer or team lead), and focus more on the responsibilities than the title.
Focus on the skills you want to build in this role. You do not need to share every long-term plan in an interview.
