Q:

Interview Question: How would you assess your own performance when working as part of a team? 

I recently went for an interview for a job where I would be working as part of a team and I was asked the following question: "How would you assess your own performance when working as part of a team?"  The question had me completely stumped if I'm being honest. 
Does anyone have any idea how I should have answered the question?  Or even the right answer to the question for that matter. 
I've asked this question on other Q&A websites and a lot of the reply's mentioned the use of peer-reviews; however, if your read the question carefully, you will see that it refers to assessing your own performance.  Obviously peer review is using others to assess your own performance. 

A:

Is this explicitly a process quiz question? " How would you assess..." more commonly means "Would you assess... as good or bad, and why". 
If you aren't sure what question is being asked, ALWAYS ask for clarification.
