Do you think that you could have done better in your last job?

This question tries to assess your engagement level in your current job-profile i.e., how well have you evaluated all the aspects involved in your profile. The interviewer(s) seek to know how do you judge your own performance.
This is a tricky question to answer. You need to be diplomatic while answering this.

Following are some alert points embedded in this question:
1. Tell them about how well the job profile suited you and what made you choose that profile in the first place.
2. Speak about your recognition and rewards that you earned while working in that job.
3. Remember that there always is a room for improvement in a job, irrespective of it being a clerical level job or a senior level job. Hence, DON’T let your answer to this question to be a straight ‘no’. This will make you sound arrogant and over-confident.
4. There is no harm in accepting your mistakes or shortcomings; what is more required is your urge to correct them and improve. Hence, tell them if you identified any such scope of improvement in your last job. However, support your answer by stating how you wish to incorporate the improvement in yourself.
