Nice to have (Preferred Qualifications):

Instructions are sent at 00:00 BRT.
This first challenge (via Google Forms) must be completed within 24 hours.
September 20th (Saturday): Candidates who successfully pass Phase 0 will receive instructions for Phase 1. This next stage, consisting of cultural and logical assessments, must be completed on this day.
September 21st (Sunday): Successful candidates from the previous stage will receive instructions for Phase 2. This final challenge, a specific technical deep-dive, must be completed on this day.
