🧭 1. What is the 30-60-90 Rule and Why is it Vital in the USA?

In the competitive U.S. labor market, the first three months define your perception as a professional. The 30-60-90 rule is an integration strategy used by headhunters and recruiters at companies like Google or Microsoft. This plan structures your first 90 days into three phases: learning (days 1-30), contributing (days 31-60), and initial leadership (days 61-90). Applying it demonstrates professional adaptability and reduces the anxiety of the probationary period.

Development:

📅 Days 1-30 (Learning):
- Listen more than you speak.
- Study the employee handbook and the company’s mission.
