I applied through an employee referral. The process took 3 months. I interviewed at Sand Cherry (Denver, CO) in Dec 2015
Interview
The first interview was with the HR Manager followed by two face-to-face interviews with Sand Cherry Sr. Consultants. They look for cultural fit more than technical skills. I would highly suggest reading Patrick Lencioni's Naked Truth to get a clear picture of Sand Cherry - it truly describes this consulting firm.
Interview questions [1]
Question 1
The questions focused on past experience and transferrable skills. It was mostly behavioral so the interviewer could gauge cultural fit.
