This one is a negative  question. It tends to assess your level of self-awareness. It enables the interviewer  to get an insight into your character. 
The word ‘criticize’  might enrage you for a moment but you need to keep yourself calm. How fast you  lose your temper is what the interviewer is trying to assess here. So, don’t  lose your composure. 
The following suggestions  shall help you prepare a wise answer to this question:
  1. Don’t say that you  have never been criticized. This shall make you sound arrogant and  over-confident.
2. Tell them that ‘I seek criticism as an  opportunity to improve my work’. There is no better way to improve than being  straightly told what your shortcomings are. 
3. Give them an example from your work-life.  Mention about how the criticism that you faced was converted by you into an  opportunity and resulted in making you stronger and better. 

Now, it’s time for 'participation':
*Assume that you are sitting in the interview room now.
*You have been asked to ‘Tell me about a situation when your work was criticized’. Go ahead; give it a try on how to answer the same. Post your own answers and get them reviewed .

Tell me about a situation when your work was criticized?
