What is the best way to answer the "why should I choose you" questions at interviews?

If you thing I am on par with my other counterparts as regards educationalqualification and other inherent qualities. Well, I can only claim to possess a few strong attributes which would make me a worthy candidate. a)      I have encountered failures & setbacks in life but with the support of parents, friends and self motivation I have emerged a stronger person.b)      I am a quick and enthusiastic learner.c)      Besides, these things I have good communication skills & ability to deal with people easily.

You answer should be so positive and politely which explains & meets as per job requirement and the interviewer should convince easily.

Candidate needs to show commitment to potential employer with positive attitude to challenges. To prove that he/she first of all enjoys the process not the result. 

 its a tricky question and shows that the questioner  doesnt have standards to follow so based on what we may say he/she may have the final answer whether he will choose us or not anyways what i think is best possible answer is to summaries what we have been saying during .the whole interview 

This is the most important question in any interview. You need to be prepared and gather all energy to answer this question as this would be your ticket onboard . The key to answer this is to express how much you can contribute being in the position you applied for ex: List out all your core competencies required for the position . Now tell the interviewer that this job means a lot to you and list down few personality traits that you poses which you think might be useful for the position you are applying for.

If you have to answer this question, probably things was going wrong in the interview earlier. So, try to fix the job earlier in the interview, because the answer ti this question is always the same and everybody gave the same answer .... because I can...., I know....., my skills ......, my knowledge ..... my experience .... and so on ....!

first tell how your x years of experience where your roles and responsibilities are matching the one required for job you have applied then the education or degree or any certificate you hold is one of the requirement of the job and finally your strength and weakness relate them in such a way that the interviewer gets impressed by your answer.

strength, consistence, activities to expend the businesses beyond the responsibilities,  self responsible as doing own business like " Work like a worship with purity"
