Oftentimes, it takes people longer to get to where they want to go in life than others. The candidate should be honest with the interviewer and discuss how their career is going, and how things may have changed over time. If the candidate is completely changing careers and trying something new, the interviewer wants to know what has influenced the change and why they believe this job is ultimately going to help them achieve success in the future. The interviewer is also looking for someone who is confident of their future, instead of worried about the past.
