Hi Silky,
Different levels/types of interviews are there, and they vary depending on the type of initial interview call and the type of company as well. Assuming it's a first-level technical interview for a Computer Science Graduate, please let me know if this interview is part of campus recruitment for which you have already cleared the written test, or if it's part of off-campus recruitment for which you have already cleared the written test, or if it's a direct technical interview and you have not given any written test. If it does not fit any of the above criteria, please specify the type of interview. Also, please specify the type of company too (Indian IT Company/MNC/Indian Non-IT Company/MNC Non-IT Company).
One thing that really matters in all types of personal interviews is your presentation of yourself, which includes dress, confidence, and knowledge.
Regards,
