I applied through an employee referral. The process took 6 months. I interviewed at Black & Veatch (Overland Park, KS) in May 2013
Interview
It took over six months from interest to job offer. I went through a phone interview and then a couple of interviews with the last one being the longest with several interviews in one day. They paid for my trip including plane fare, hotel and meals.
Interview questions [1]
Question 1
Nothing they asked was difficult. The one interview question I remember was to describe my work history and skill sets.
