Show that you have done your homework
Try to relate what you know about the company when answering questions. Potentially mention names of famous campaigns or some interesting fact that you noticed. Link your expertise with the company's requirements and thus promote yourself to the interviewer. Be careful though: Don’t overdo it. It is very important that you promote your accomplishments in moderation. You dont want to look like you are trying too hard or that you are speaking like you have prepared your lines from home. The interviewer can tell when you have studied too hard, when you are cool and when you are underprepared.
Always follow-up with a thank you email after the interview. The best timeline would be within 24 hours after the interview. You can send a thank you note even after a phone interview. This is an effective way of showing thoughtfullness, effort, and interest for the job. You can also include any details you may have forgotten to mention during your interview. If you interview with multiple people send each one a personal email, (if you dont have their email address, then probably search that on linkedin, there’s always a way). You could also send a follow up email if you haven’t heard from the hiring manager after a long time. Maybe your CV got lost somewhere in the middle, who knows? An extra email wouldn’t hurt anyone and especially not you.
Review the job description
The first step in the preparation process should be to go back and review the job description. Make sure to keep an eye for the following:
Duties and tasks
The job title and department will give you an understanding of the major purpose of the position and where the role fits into the organisation.
Read and review the job description very thoroughly and be sure to align your competencies with the skills required for the job. Then, try to prepare for questions around your experiences, similar tasks you have performed in your previous jobs or even duties you have undertaken during your university years.
Research the company
Organisations look to hire people with similar values to those of the company culture. Researching the company before an interview will give you an insight into the organisation's future goals and plans and being able to discuss these points will make you seem like a long-term investment to your future employer.
Always, check the company website. You can uncover a lot of different, interesting facts. Have they expanded recently? LinkedIn is also a good source of information. Check for the company’s products/ services, its customers basis, culture, or activities.
