Having employees interview their potential new manager is a terrible idea. Here's why from a senior leader at Amazon.

• Brandon Southern is a senior leader at Amazon and former head of analytics at eBay and GameStop.
• He writes that its a terrible idea for companies to have employees interview their future managers. 
• Southern writes that employees have a conflict of interest. 

As a senior leader at Amazon and a tech veteran for 20 years, I've been involved with hundreds of interviews across several companies. When a new management position is opened within a company, there's one interview practice that has never made any sense to me — having direct reports interview their future manager.
