Dear Reddy, make sure that your CV is updated. Dont use fancy email ids. Dont write anything in your CV for exaggerating. Stick only to what you know. Be genuine and honest. Admit if you do not an answer for any question in the interview process. Remember to brush your communication skills. Appear confident. Remember that you are one among many candidates who are appearing for the interview. So you have to stand out with yiur answers. Be polite. Read about the company and job description before you are going for an interview. Make sure you draft your 'Tell me about yourself', 'Where do you want to see yourself in 5 years', 'Your strengths and weaknesses' answers. When the interviewer asks do you have any questions, ask what is the kind of profile and how does a day in this role look like.
