> The vast majority of side projects I see from applicants are one-off toy projects that have the luxury of starting from a blank slate, haven’t been built in a collaborative environment, aren’t hosted for significant traffic, and often aren’t user friendly enough to be used by anyone other than the author who knows all of the right commands and steps to get it to work. And every one of these bullet points can tell you a lot about how good a developer can be. Do they know the limitations of their project, what is it that they wish to have done better, why wasn't it done, why did they stop developing, etc, etc... there are so many questions to ask based on the individual contributions that give you a lot of good information about how well a developer can work. When working as part of a team a lot of developers' short-comings can be hidden by the achievements of the other members. From my point of view (as not a hiring manager) the only time when the achievements from a work environment are more important than the individual ones, are when we're talking about how well someone can work with others (which is mostly a soft skill you can gauge from conversation alone) and when individual projects can't really exist in the context of the technologies the team you hire for is working with, and you require previous experience with them.
