Everyone wants to believe that they can handle every project, but the reality is that most project managers are best suited for a narrow project management role. If you tell your future employer that you love working on everything, that communicates that a) you might not know what you're talking about or b) you're unwilling to communicate weaknesses. Neither of these traits reflect well on you.

Instead, be honest. Are you more of a software development person? Do you do well with creative media campaigns? Would you rather lie down and die than work on a construction project? Let your interviewer know; both they and your future self will thank you for it.
