Product Marketing Interviews

I had my first interview in a long time recently and fumbled my way through it. How can I get better for next time?

I usually come across an interview round wherein I am handed the task of preparing a mock GTM plan for a product. I find it pretty vague as expectations vary widely and I am usually confused about what all to include and how to represent. Is there any example?

Also, how to actually show its success, as this is something that may take awhile before seeing a growth trend and can you directly actually attribute a particular success metric on messaging?

e.g. do we need to do a case study, draw insights from looking at data, etc.

Should I just use one general resume or are there different versions of it?

Writing samples? Case studies?

Which materials/key points/key themes you work on for them to know how to show your tool is better that the competitors'?

Recruitment

My most recent experience is doing partner marketing at Toast, which was on the same team as product marketing, doing partner product launches, running our partner program, doing sales enablement, and planning/executing campaigns. I have experience in content marketing at Tripadvisor (where I helped grow product adoption of a new product), and project management experience at the WiMAX Forum (where I empowered member companies like Hitachi, Siemens, GE, and more to bring WiMAX technologies to market as part of their product offerings).
