This is the type of question many interviewers will pose as a means of gauging your work or management style. When being asked to choose only one response, you can generally assume that big-picture people would generally be considered better management material whereas a detail-oriented person would be better suited to smaller-scale projects.
Obviously, it’s important to possess both qualities to an extent, but much of what the question is asking is whether you can make a clear decision. Make sure your response satisfies both aspects of the inquiry.
Assuming that you wish to advance to the highest possible position in your future occupation, you should seek to illustrate your big-picture focus:
It’s okay to possess keen observation skills for the details, but make sure you choose one personality type and keep your response focused.
Even though you need to make a clear choice, don’t strive to stand too far to one side of the discussion. Every big picture involves plenty of details, so you need to have both types of vision.
You are who you are—if you’re truly detail-oriented, don’t suggest otherwise. Just keep in mind certain types of jobs are better suited to certain types of people.
Use the following example as a starting point for fashioning your own response to this question:
It’s definitely important not to lose sight of the details, but I personally see the big picture first and foremost. I’m used to recognizing opportunities on a larger scale and putting the right people and processes in place to make the greatest impact. I do enjoy having opportunity to focus on the finer details but I feel my instincts and talents are best suited to big-picture focus.
This response doesn’t disregard the details, but displays confidence and focus in one’s abilities to act at the macro level.
