I have been working at Unimin full-time (More than a year)
They offer great benefits with competitive pay and there are many knowledgeable coworkers and supportive supervisors. They are a twenty four hour a day operation.
Being a twenty four hour operation and a place that retains employees for long periods of time, it is hard to move up into a day position and have a normal life.
I applied through a recruiter. The process took 4+ weeks. I interviewed at Unimin (New Canaan, CT) in December 2016.
Interview process was good and well orchestrated. At least for me they conducted two team interviews. I was not asked specific questions about my expertise, but instead more process related questions. The internal recruiter was great. I was put off (and declined) by a request to take a series of quizzes and tests. It would have been more appropriate to dig in more during the interview process. My work experience has, as an example, min max calculus (network design) in it ... and the quizzes would be used to test my knowledge about whether I could interpret a graph.... it just seemed very, very silly. Other than that - it seemed like a nice place to work, with good and smart people.
