I had to complete two online assessments that evaluated 1. Your math skills (easy math but limited time) and 2 your personality (Think of Meyers Briggs) I believe I had 3 interviews. 1. With the director or VP - informational 2. With a manager and a current Applications Engineer. I used this time to ask a lot of questions that I had, and they asked a few customer service questions along with a few technical (think troubleshooting approaches & conceptual physics questions) 3. Meeting with 1 applications engineer + another employee that was less technical and more gauging your personality. It was very obvious when they starting asking questions such as what is your favorite book?... etc

The first half of the interview was by two people who mostly asked through my resume and a bit of technical questions pertaining to different scenarios where you had to solve a problem for the customer. The other half was taken by two different people. The questions in this one were more personal. I received a rejection call soon after the interview although I thought it went really well. I don't think the reasoning I got for getting rejected was accurate since I had the experience required as per the job description. I believe it was based on there office culture. They need people who are exactly like them. Majority of the interviewers were quite young with little experience.
