You then decide on a solution.Following steps for problem-solving and decision-making can be very helpful.- Define the problem to be solved and decision to be made.- Gather the necessary information. - List all possible choices. - Consider possible outcomes for each choice. - Check out how you feel about each of the choices. - Relate the choices to your values and priorities. - From the possible alternatives, choose one. - Commit yourself to your chosen decision and disregard the others. Concentrate your energies   in one direction. Once we made our decision, we must focus all our work on that itself.- Take steps to turn your decision into positive action. - Evaluate your progress from time to time. Change your decision if necessary.

उत्तर :
व्याख्या :

In most cases, you will have no idea who you are competing with for a particular job. So this type of question really gives you a chance to open-up your strengths as a candidate with an emphasis on any assets that might separate you from the typical applicant. Think about what you bring to the table that you truly believe is unique - the easiest way to do is to think of your own personal stories that demonstrate your work ethic, skills, and dedication. Most people have some or all of those skills, but the unique stories are what make people stand out in interviews.
