Forterra Embedded Software Engineer interview questions

The interview process was smooth and well-organized. It lasted about four hours, following a tour of the company’s facility in Clarksburg, MD. There weren’t any particularly challenging questions, and overall, I felt confident about my performance. However, I believe I wasn’t selected due to my immigration status, as the position requires U.S. citizenship. I do wish this had been made clear at the outset of the process, as it would have saved time and set the right expectations.
