“I loved the open, family-like culture that is present at this company. HSC is a true example that if the employees enjoy their jobs, they are more efficient and skilled at what they do; the company did a great job of combining hard work with fun, which allows for small incentives throughout the work week. My projects revolved around maintenance of the plant equipment, thus requiring a great deal of critical thinking and problem-solving on a thermodynamic engineering level. Throughout the summer, I always had someone to help answer any questions or inquiries of mine, and I engaged in a lot of insightful discussions with employees of all different roles and skill levels across the plant. Overall, this was a fantastic internship experience and a perfect way for me to gain exposure to the many facets of manufacturing.”
