While preparing for an interview in a job at the Data center in any company, one must pay attention to whatever he/she has studied and learnt practically. One must be confident about the experiences during internship and knowledge about the field. News and updates regarding recent and on-going developments in the field should also be read and remembered. This would give an impression that the job seeker is serious and knowledge-thirsty.
It is not always about being a hard worker but also a smart worker, and one should be able to project the skillset well so that the interviewer selects him/her.Smart appearance also matters because everyone prefers presentable employees.
