I applied online. The process took 3 months. I interviewed at H+M Industrial EPC (Pasadena, TX) in Jan 2017
Interview
They email you an invitation to come to their office to take a 100 question, multiple choice piping quiz on a laptop and you have one hour to finish it. The first 50 questions are easy, the next 25 a senior designer should know. Then the last 25 are either trick questions or things that an engineer should know.
Interview questions [1]
Question 1
If a company is making $50 million every year, then why are they still operating out of their old rinky-dink Mickey Mouse buildings way out in Pasadena?
