You have an initial round with the recruiter then proceed past the screening to a 1-1 interview with the hiring manager. Depending on the outcome, you will proceed to a panel interview

Phone screening, then phone interview with an engineer, which was mostly about teamwork skills and to describe myself and my goals. Then they invited me onsite for a site tour (with other candidates) and a several-hour long interview process with four employees. The questions ranged all over, from solving simple mechanics puzzles to describing my teamwork skills, project skills, and what some of my most intense analyses have been in the past. At one point, they asked me to draw a free-body-diagram. It all well went well in my opinion, I answered every question in detail and in a way that demonstrated my strengths. However, I was aware that another candidate was equally skilled and had a higher education than me. I was fine with the fact that I was truly bested for the job, but I was shocked by the fact that they completely ghosted me after the interview day. No emails, no responses, no rejections.
