I had previously applied for a sales role, but another candidate had been chosen before my in-person interview. I was then contacted about one month later to interview for the Technical Marketing Engineer position. To my understanding, the interview processes are similar, if not identical. I had to pass each of these in this order to be hired: 1.) Technical Aptitude Test (55 basic physics/engineering questions in 25 min) 2.) Phone Screen (quick, easy, straightforward) 3.) Video Interview (tricky-- you are given questions and must record your answers to them in allotted time) 4.) Personality Test (they review your video interview if you pass the personality test) 5.) In-person interview (sales presentation on one of their products... a sales position additionally requires a sales role-play where you try to sell a pen) Overall, I believe the interview process was (excessively) thorough. If I could change anything, I would suggest that the personality test be administered prior to the video interview-- the personality test is probably the biggest "hard stop" in the interview process: if you don't pass to their standards, you're immediately cut from consideration for the role, and your video interview won't even be viewed. I also suggest working through a staffing agency, as they were able to guide me through the difficult process and help me prepare well.
