30-Day Note
A one-page written summary delivered to your manager at the end of month one. Three sections: what you learned, what surprised you, what you will focus on next.
The 30-day note is the highest-leverage piece of writing in your entire onboarding. Most new hires either skip it or pad it with 4 pages of impressive-sounding learnings. Both fail. The version that works is short, structured, and ends with one specific question.
Three sections, five bullets each. End with the question 'am I focused on the right things?' That single question forces a yes/no read from your manager. If yes, you have an artifact you can point to all year. If no, you have just bought yourself a 30-day course correction at the cheapest possible time.
Send it the day before your week-4 1:1, not the day of. They need 24 hours to read it before the meeting.
