As said in a lot of the replies here, it simply mean for the interviewer : "Can this person work in our team" outside of the inherent quality of the person. For programmers for instance, are you the type that want to documents every single line, create complicated interfaces ? Are you a hacker type, delivering as fast as you can, knowing that you'll be able to fix it later if a new requirement comes in? There's nothing inherently wrong with any of that. Depending on the scale of the products, the tech debt and the organisation, it's obviously going to be different. You don't hire the same developer to work on a startup prototype than to work on a 5 years old enterprise application. Basically, you're asking: "okay, that person has the necessary skills. But will they be happy working with us and will we be happy working with them". As other comments mentioned, it can be other thing than technical culture fit. Is can be taste in culture for instance. Is the team a bunch of geeks that regularly play games together and would not fit well with someone who likes sport for instance. Or are they heavy drinkers, having a pint every evenings, and you should fit into that too. If the company has issues (ever-changing requirements, overtime is the norm, technical debt is never addressed etc.), it can also be a way to predict if the candidate will be able to wistand those, or will leave before the end of their probation.
