I applied online. I interviewed at Celanese in Apr 2018
Interview
Scheduled an initial phone screen with a talent manager who basically gave me full run down on the company and asked one or two questions that the hiring manager was looking for. I then did another phone interview with the VP of Human Resources in which she asked me a few basic questions and then told me more about the internship. I was told that they would contact me to schedule an in-person interview but never received a response.
