I applied through an employee referral. The process took 2 weeks. I interviewed at PPG (Pittsburgh, PA) in Aug 2014
Interview
Phone screen with a technical recruiter, followed by a phone screen with the hiring manager. All questions were pretty generic and not overly technical. Most questions involved prior experience and what you are looking for in the company as an employee. Final interview was onsite with multiple managers and a tech screen with other developers. Most of these questions were behavioral in nature (How would you handle this? etc.), tech screen was more in depth technically, but mostly covered general topics that a programmer should be able to handle easily.
