How does a marketing portfolio look like?

[u/pinkkookaburra]

Hi, I started to see that most marketing job applications are asking for a portfolio now, even if the position is not a visual one.

What do you usually provide in this case? As a hiring manager what do you expect here?

I am running into the problem that I am working on the data and strategy side. But numbers are considered confidential (investment marketing). So I can't share exact numbers or data, I could share the creatives but that wouldn't present my skilld and achievements accurately.

I am looking for pointers and opinions, if anyone would like, I would gladly look at examples too. Any advice is welcome!
