Production Manager Question:

It is simply not possible to address everything needed to excel in a product management role in one 45-60 minute interview. It's also not realistic to subject candidates to extremely long interview processes. In a tight job market for top talent, great candidates won't have the patience.
The coordinated team approach we recommend allows each candidate decision to be made with up to 4 times as much data. It also ensures balanced coverage across all key areas.
In the alternative/classic approach, each interviewer decides individually using only his or her 45-60 minutes of data. And since interview questions are not coordinated, there is a high risk that some key areas are never addressed.
