I worked at Holcim (US) full-time (More than 3 years)
Very flat and international organization with friendly and intelligent people. All depends on the department you work at though.

Advice to Management
Management should care less about themselves and more about their employees' growth and development. Only verbal praise does not count.
I applied through an employee referral. The process took 6+ months. I interviewed at Holcim (US) (Sainte Genevieve, MO) in February 2015.
A general phone interview followed by an in person interview and plant tour. They rely on the S.T.A.R. interview method, so make sure to review that and have answers prepared to questions they might ask.
