First of all, good luck!
Next, assuming that you already have experience in growth or performance marketing, I think the best thing you can do from now till Monday is to analyse all the company’s communication and growth channels with their users and customers (retail, social media, PR, EDMs, long-form content, SEO etc). If you spend the time to learn what they’ve done and what they’re doing now, you can easily spot trends in what growth experiments or campaigns they’ve run. What stuck and what was killed. From there, you should be able to figure out how your skillsets and experience can add value to their cause.
Lastly, go to youtube or Spotify to watch and listen to how growth and performance marketers talk about or present growth in a scientific manner.
Hope this helps. All the best 🙂
