LivingSocial is growing like gangbusters. That means they need to hire plenty of sales people. As a result, the company developed a unique way to rapidly increase their headcount. Almost every week, LivingSocial flies between 20 and 30 prescreened candidates to its headquarters in Washington D.C. for a day-long series of interviews. The "super sessions" cover everything from sales aptitude to cultural fit. Current and former employees likened the process to "American Idol" or "The X Factor."

Mandy Cole, head of sales, and Jennifer Trzepacz, vice president human resources, were kind enough to talk with us about what goes down during the super sessions. Their words follow.
