After applying through LinkedIn I received an email from HR asking to set up a phone interview. However, HR never specified the call would be with the hiring manager (Group Account Director). The GAD asked standard questions and the interview mainly focused on culture and experience.
The next step was another, longer phone interview with the GAD and Head of Media. These questions were more direct and focused on specific skillsets, technologies and past experiences.
The final step was a presentation (15 minutes focusing on media trends in retail) via video conference with the Head of Media and President, as well as a math test. These steps were never discussed during the initial stages, and were only brought up in between interviews 2 & 3. Additionally, I was asked to create the presentation within 24 hours, which looking back I should have asked for more time. The ask was easy and clear enough, but even the Supply team didn't seem to be organized during the presentation. This was intended to be a role play with me giving the POV presentation to a fake client, but the President did not seem 100% aligned asking "candidate/interview questions throughout.
Advice: clarify each and every step and push back on timing.
