What the Community Says
Owens Corning holds a 3.5/5 rating on Indeed from over 1,500 reviews. The company's pay-and-benefits sub-rating is notably stronger than its overall score.
Owens Corning scores 3.5 out of 5 on Indeed across 1,524 reviews, with pay and benefits earning a stronger 3.7. The work wellbeing score is 67 out of 100. Reviewers highlight a clear sense of purpose, the ability to learn new things, and solid benefits. For a Fortune 500 manufacturer that has been on the list every year since 1955, that pay-and-benefits rating is consistent with the stability you would expect.
The entry-level production floor starts at $17.50 to $22.50 per hour, while maintenance technicians earn $31.33 per hour. Engineering interns are estimated at $22 to $30 per hour based on peer benchmarks from 3M, Dow, Corning, and Honeywell. Reviewers note great management at some locations and strong training, but also flag physical demands like heat exposure at manufacturing plants and 12-hour shifts. The intern experience at HQ or the Granville R&D center is likely quite different from the plant floor.
OC's 2025 Campus Forward Best in Class Award recognized its recruitment strategy, candidate experience, and internship programming. Employees who have reviewed the company describe friendly coworkers and competitive pay for the building materials sector. The main concerns center on management communication at certain locations and overtime dependency. For ME students, OC is regularly listed alongside 3M, Corning, and Dow as a desirable manufacturing internship destination.
How Do You Stand Out at Owens Corning?
First, reference the company’s unique position as the world’s largest fiberglass composites manufacturer. Connect your engineering skills to a specific product challenge, such as how lightweight composites reduce vehicle weight or how insulation R-values are engineered to meet evolving energy codes. Second, demonstrate knowledge of OC’s sustainability commitments: the company ranked number one on Corporate Responsibility Magazine’s 100 Best Corporate Citizens in 2022 and has been on the Dow Jones Sustainability World Index for six consecutive years. Discuss how mechanical engineering contributes to emissions reduction, recycled content in shingles, or energy recovery in manufacturing. Third, prepare for a plant-based interview by brushing up on safety culture (PPE, lockout-tagout), lean concepts (5S, Kaizen, value stream mapping), and the practical mechanical problem-solving that OC’s manufacturing floors demand.
