This question usually goes better when you stop treating it like an invitation to recite your whole biography.
Use a present-past-future structure
Start with what you do now, move briefly through the relevant background that got you there, and end with why this role makes sense as a next step.
Stay tied to the role
The strongest version is not the most complete one. It is the one that helps the interviewer understand your fit quickly.
Bottom line
A good answer is selective, relevant, and easy to follow in under two minutes.
