While I was at eBay, the product management team grew to over a hundred people. When the company conducted a Myers-Briggs profile assessment, results revealed that half of those product managers were INTJs. The INTJ personality type, often called the “Architect” or “Strategist,” makes up only 2 percent of the population (and less than 1 percent of women). I was one of those INTJs
For so many of the product managers to share such a rare personality type meant that there were too many like-minded people in the product team. Because like-minded people tend to hire like-minded people, it was a self-perpetuating problem. I didn’t recognize it at the time, but upon reflecting many years later, I was part of the problem. I was guilty of allowing a bias toward “Architects” and “Strategists” to shape my feedback on candidates, and I hadn’t yet come to appreciate the importance of bringing in a fresh perspective to a team.
Thankfully, once our leadership recognized this overconcentration of a single personality type, it took an active effort to hire more diverse candidates in product management, and I learned a tremendous amount through my interactions with those later hires. I honestly don’t think that I would have ever gained an awareness of my own blind spots, nor a desire to address them, without that experience of working with a more diverse peer group.
