How important is it to find a niche in ID?

I found myself wondering this same thing a few weeks ago being a student that’s still unsure about what goes on within the industries of industrial design. Specifically, I wondered how people ended up in highly regarded studios like BMW Design Works or Peugeot Design Lab versus companies like Frog or Ammunition, did they have to tailor their portfolio and focus all of their work that way? Is it a skill level thing? I’m still quite unsure how people end up at the companies they get to, especially in the automotive field. But nevertheless these answers are great!
