It depends on the role and what the side hustle actually is. If it's something that could create a conflict of interest with the job you're interviewing for, then yeah, you should mention it - especially if there are non-compete clauses or if it directly competes with what the company does. Better they know upfront than discover it later and feel like you hid something.
For most side gigs though, employers don't really need to know the details unless they ask about your availability or time commitments. If the job requires you to be on-call or travel constantly, and your side work might conflict with that, definitely bring it up. But if you're doing something totally separate that won't affect your performance or schedule, it's usually fine to keep that private. Just be honest if they specifically ask whether you have other income or work arrangements.
The main thing is don't lie if asked directly. Interviewers sometimes probe about outside work to make sure there's no conflict or that you won't be distracted. Give a straightforward answer - what you do, roughly how much time it takes, and why it won't interfere with the job. Most people get it; side hustles are pretty normal these days.
The safest move is to disclose it only if asked directly about other income or commitments - don't volunteer it unprompted. The reason people say "it depends" is partly right, but honestly most employers don't care about side income unless it affects your availability, creates a legal conflict, or you're working for a competitor. If the side hustle is something like freelance writing or consulting in a completely different field, it's rarely relevant to mention. But if it's something that could pull your attention away during work hours or involves non-compete issues, that's when you bring it up - better they hear it from you than find out later.
The real question to ask yourself first is whether your side work could affect your availability or focus on the main job - if it won't, there's genuinely no obligation to bring it up unprompted. One practical angle nobody mentions: check the job posting and company culture beforehand; some places openly encourage side projects (tech startups, creative industries) while others treat them as red flags, and you can calibrate your openness based on that. If it does come up naturally in conversation about your skills or experience, frame it as something that taught you specific things relevant to the role you're after. What kind of side hustle are you running, and is it in a similar field to the job you're interviewing for?
