The interviewer expects you to describe your experience from job one until now. They aim to know how things have made you grow from a professional point of view, and as an individual too. You must include important soft skills like communication and adaptability in your answer. Nobody starts perfectly but catches up on things with time. Talk about your communication and leadership skills have improved for the better over the years. You can also talk about the technical skills related to your field that you have acquired over time. You must align your answer with the ideas of the company. Avoid criticizing or blaming previous employers. Every job teaches you something, so make sure to convey your personal and professional skills confidently.
