It was a continuous discussion between an interviewer and interviewee on a face to face interview. In between that discussion:
Interviewee clarified his question – “Are you talking about my professional success ?, professional success in terms of what , means I got any award or I promoted recently or how I contributed within the team or I written any patent or Technically I invented something”
Interviewer reDefined his question and said – ” In general, How you verify that your performance is good within the team ?, Or how you satisfy yourself that whatever you are doing that is professionally skilled ? Or how you evaluate that you are professionally successful within the team ?”
I measure my professional success by self-evaluation and feedback from related teams for performing the work related tasks that involved my functional and technical skills as mentioned above. That self-evaluation always brings several areas for improvement and success to some extent.
