Can You Solve the "Impossible" Job Interview Riddle? | The Curious Math Lab

10 candidates face an ultimate final interview test: each is given a red or blue badge without knowing their own colour. Each person can only see the badges in front of them—and at least 9 must guess correctly for anyone to be hired. Can you figure out the winning strategy before the time runs out? In this video, we break down the clever mathematical concept of parity and show how a single coordinated guess can guarantee that 9 out of 10 candidates walk away with the job! ⏱ Timestamps: 0:00 - The Impossible Interview Setup 1:15 - The Rules & Stakes 3:28 - Pausing to Solve the Riddle 4:36 - The Parity Breakthrough Strategy 6:51 - Walking Through the Solution Step-by-Step 10:19 - Key Takeaway & Final Thoughts 🧠 Can you think of another variation where all 10 could be saved under different rules?
