Introduction of course

ITIL® is the primary framework containing a set of IT service management practices. It aims to bring IT services closer to the needs of the customer and meeting an organization’s business needs.

Why is it important?

If you’re an IT professional, taking up the ITIL® certification course will contribute to the growth of your career in several ways. The latest model of the course is divided into five parts; each of which focuses on different stages of the ITSM (Information Technology Service Management) cycle.

Phases of the interview:

Here are the three major phases of an interview,

Phase 1: Invitation

When you apply for jobs at the organizations you aspire to work with, the first step from the employer’s side is ‘reviewal’. After reviewing your resume, if you are believed to be a good fit for the position, you receive an invitation for the interview. The invitation can be sent in various forms like e-mail, phone call, message or even a letter. However, each of them is kept professional and the same is expected from the candidate. Be sure to revert to the invitation professionally and promptly.

Phase 2: Meeting

The next phase is the face-to-face interview on the decided schedule. The main aim of this is to estimate the capabilities of the candidate and understand their personality. It is essential to make a good first impression on the employer by being punctual and professional. Highlight your strengths and very politely, accept your weaknesses. Be confident and positive but don’t over-do it.

Phase 3: Follow-up

The last and certainly not the least important phase is "Follow-up". This phase can either make or break the opportunity. It is essential to adopt a professional way of communication for a follow-up. You can either drop a mail appreciating the time provided for interviewing you, expressing gratitude for the opportunity or simply give a phone call thanking and enquiring about the job.
