Met them at a career fair and talked to some representatives about my project experiences. Received an email asking me to schedule an interview with the department head of the division I'd be working for. The interview was essentially a conversation about my technical experiences and what the department does at Rheem. No questions were asked aside from the usual "Introduce yourself", and there was a chance to ask questions. I heard back pretty quickly saying that I was a finalist for their co-op program, but the company needed to finalize their budget. After getting ghosted for a couple months, and after me regularly checking in, they finally told me that the only position they had was for next fall.
