Initial informational interview to learn about opportunities, followed up by technical and on-site. The initial interview was great, although it did reveal that my skills weren't the best match for the company. I'm more on the design/data side, but they definitely seem to need people with more technical skills (most of the positions were more technical). I think if you have a solid engineering background but also want to learn on the job and expand beyond it, this is a good fit for you.
