I interviewed at Tremco at the end of 2019. The interviews were fair and they asked thoughtful questions. I completed the phone interview, an in-person interview, and then we set up a third interview where I would meet the team. They changed the date of the third interview three times, saying that one of the individuals was sick. They then changed the requirements for the position. It seemed they weren't clear on who or what they wanted and it took them a while to figure that out. Don't expect transparency or a high degree of professionalism from Tremco.
