Wondering why you are not hired? You feel dissappointed, right? Take time to evaluate and see why you are not hired after the interview.
Here are some reasons why you are not hired :

You are late on  the scheduled time of the interview.  No matter how good you are, being late is not a good start. Being punctual is a big first step to impress your future employer.

You did not made a good impression from your prospective employer. You may have shown unbusinesslike behavior while you are in their office or during the interview.

You have talked too much during the interview.   Do not overdo the interview by talking too much  just to impress them.  As much as possible, your answers should be brief and objective.

Your salary expectation are too high for their budget.  Even if you are qualified for the position, salary is still the most important factor of your application.  Negotiate the salary well, do not overpriced nor underestimate yourself.

Job hunting can be very frustrating at times, but with preparation, organization,determination, and persistence you will surely find a  job that is right for you.
