Why interviewers ask this
Interviewers ask this to understand your genuine motivations for moving and to gauge whether you are likely to speak professionally about a future employer if things do not work out, since how you discuss a current or past employer is itself being observed as a signal. The specific reason matters less than how constructively and professionally you frame it.
What to avoid
Avoid speaking negatively or bitterly about your current employer, manager, or colleagues, even if your frustrations are genuinely valid, since this often raises more concern about you than about the situation you are describing. Avoid framing the move purely around compensation alone, even if it is a genuine factor.
How to structure a strong answer
Frame your answer around what you are moving toward, such as new challenges, growth, or a better fit for your skills, rather than only what you are moving away from. If there is a genuine, reasonable concern with your current role, you can mention it briefly and factually, without dwelling on it or sounding bitter.
