The Japanese startup Attuned devised a 55-question survey that can identify what motivates a company's employees.

The survey uses AI to gauge how much each employee is motivated by money, competition, and other values.

Wahl invited me to take the survey, so last week I took him up on the offer. Although I was bewildered by some of the questions, I managed to make it through, and learn something about myself in the process. And I left understanding why major Japanese companies like Rakuten and Denso are shelling out so much money to have their employees do the same.

Here's what the experience was like:
