I&#x27;ve had folks who just jump into the code without any planning.  It usually bites them about 20-30 minutes in.  On the other hand, I remember one guy who spent the first 20 minutes planning and only 40 coding and ended up doing better than most.<p>The point here is not &quot;Write as many lines of code as you can&quot;.  I <i>want</i> the candidate to plan - it&#x27;s a crucial part of the job.  FizzBuzz, sorts and the like don&#x27;t require much planning.  Minesweeper does.
