What will you do if you are assigned a target which is impossible to attain?

It can happen from time to time that your company's sales forecasts are a bit off. If this has happened to you in your career before, be sure to use that as an example. The hiring manager is looking for a reply that will show tenacity to try rather than deem the target impossible and give up as a result. It may not pan out well in the end, but the important part is that you exhausted all means to make it work.
