One time i received a call, and the caller had told me that i have a scheduled for a job interview.So i went to the HR and one interviewer lead me to the interview room.She asked me a lot of interviews..Luckily i answered it all at my best but certain i knew when she asked me last final question.When she asked me that "How would I describe a Red color to a blind person?" My God I was astonished on that and stared blankly.... even now i try to figure out the best of what is on my mind,,, Do you have any thing to tell me?...
