VC 1-Page Investment Opportunity Memo (Interview Advice)

Hi Everyone, 

I am currently interviewing with a top-tier VC to join their research team in a very junior role. The next step in the process is a 1-page investment opportunity memo which the team will evaluate. While I have experience with executive summaries generally, I have never written a 1-page memo. Apologies if this is an ignorant question, but is there a specific format used in the VC world for something like this? 

I am fully prepared to use a condensed research paper outline, but wanted to check here first. I am aware of the Roelof Botha leaked Sequoia memo, but that seems somewhat long. Additionally, I am aware of this template: https://alitamaseb.medium.com/a-template-for-star… . 

First-person insight here would really help. Thank you very much to anyone who reads or comments. Take care.
