Soleras Advanced Coatings interview questions

I applied through Indeed and spoke with HR, and came in to do an in-person interview at their shop in Biddeford, ME. It took a few days after the interview for HR to get back to me. I was not offered a job, even though the interview seemed to go well and HR indicated that I would fit in well, HR has not answered my email when I asked why when the interview seemed to go well. I had not yet taken a drug test or background check.
