Behavioral Technical Coding Presentation

I applied online and then had an HR interview. It was pretty basic, covering my motivations, intentions, and expectations. After that, I had a second, technical interview online with the Hiring Manager and another engineer. They asked me some basic C programming questions and had me review some code to find errors. The third stage was an onsite interview that lasted about 5-6 hours. This involved giving a presentation about my experience and achievements, and then going through a few more interviews, one of which included live coding.

Behavioral Technical Coding

I chatted with a recruiter at a career fair, then had an interview on campus a couple days later. It was a pretty standard interview where they asked about my resume and experiences. He said he'd put me forward for the next step, and I got an email about a week or two later. They flew me out to Neenah WI (they covered gas and hotel), and I had an all-day interview. It included a tour, a meeting with HR to go over benefits (which I found really odd), and a couple of skills tests. One test was about the software development process (covering requirements, design, implementation, etc.), and the other was a programming test. They mentioned they use the same programming test for all skill levels, and I didn't do too well on it. I got an offer via email a week later.
