The advertising interview is not like other job interviews. It's special. It's different.
And often times the importance of it is overlooked, especially by students and juniors.
Over and over again you're told that the only thing that matters is your book so it's not completely surprising that students sometimes neglect the details that would make a good interview great.
The truth is, having a great book is paramount. However, having a good interview will make your work shine that much brighter and a bad interview will have the inverse effect.
The internet is a tad short on resources dedicated to this particular topic though. So even if an eager young creative was savvy enough to look up tips for acing an interview with their dream agency, they would probably come up short. Sure, there are loads of documents out there that'll help you get ready for an interview at a bank. Or an accounting firm. But instances are probably far and few between of Creative Directors asking applicants to list three of their strengths and three of their weaknesses. The advertising interview is a special kind of beast.
Fortunately, some of the brightest in the business agreed to share their tips for acing your next agency interview, beyond just having a great book. So good luck and remember: you've been warned.
