Interview OK but not selected

For a professional facing interview rejection is tough as he/she usually expects a positive outcome from an interview.
Interview rejection is often a hard fact of life. Most of us have faced it at some point in our lives. Facing it is an ordeal as we are usually hopeful after an interview and then the dreaded NO disappoints us. But this is not entirely a lost cause. Everything is fine and not falling under the above mentioned category then there can be a problem at the employer’s end. Therefore interview rejection can in fact be a good inspiration for you to succeed in life and get a better job than the rejected ones.
Facing rejection often helps you to rework on your interview skills and make improvements as a professional. The candidate must know and be convinced that he / she is not the only applicant particularly if it is the preliminary round. That will help the candidate to be less worried about the outcome of an interview.
      
        Here are a few things to keep in mind when the hour comes. Never doubt about yourself.
Taking rejection in one’s stride is not everybody’s cup of tea. However, this is the single most distinguishing factor between the go-getters and the losers. To get disheartened after rejection is indeed natural. But what is important is to move on. The essential technique is never doubt yourself. Re-evaluate your strengths and weakness and take this failure as a stepping up towards future success. Always remember your skills are your assets and a rejection from an employer cannot dismiss them.
  Recognize your weakness from the performance during the interview. You need to confront the rejection and own it. Once you recognize your weaknesses and shortcomings you will then be able to positively address any gaps or weak points in your knowledge experience, skills and techniques.
Although it is easier said than done, you need to deal with rejection and move on as quickly as possible. Give yourself a day. Once you’ve calmed down and regained your confidence, it is then time to look back and improve.
Always take the opportunity to gather feedback and gauge whether there are areas that you can improve upon. Learn from the mistakes, correct them and look forward. If you know you were nervous and may not have answered questions, well, then you know you can work on it in the future.
Accept that it may not have been anything personal. You may not have as much experience as another candidate or you may not have the requisite qualifications. On the other hand you could also have been too highly qualified and the interviewer felt   that you wouldn’t have stayed in the job for long. Remember, failure is a necessary step on the path to success.
Take rejections as an opportunity. Always remember the job you missed is not the last job on Earth. With so many fields and job profiles making themselves available every year, job opportunities are waiting in the wings. You just need to be on the lookout for newer ways or jobs in life.

   Find a creative way of releasing your frustration. Go to the gym or engage in a hobby like painting or dancing to dissolve the frustration of a rejection. Not only will you feel better you might also come up with newer ideas of self-expression.
Move on with optimism and do not brood and get stuck with the rejection, discuss it with family friends or whoever you are comfortable with. Vent   out your feelings. Look ahead with a positive attitude and be self-confident. Do not leave rejection just like that, it’s part of job search. Keep looking out for new opportunities and never give up. If you feel depressed for a long time, then take professional help. Successful job hunters use rejection as a tool to push further and drive them towards success, so look ahead with optimism. In the next interview learning from the previous job rejection perform well and avoid disappointment.
