The first step is a basic online comprehension test. Basic knowledge questions, problem-solving, matching patterns, etc. The second step is a live interview. Nothing technical in this one, they just want to get a sense of your personality. They reiterate that traveling is a big part of the job. Seemingly trying to scare you away a bit. The third step is a final interview with some previous field engineers. There are some technical questions regarding circuits. They have some role-playing where you have to pretend you're troubleshooting a T.V issue. And afterwards they just talk more about the traveling aspect and give you time to ask questions.

Got emailed a few days after applying with a link to take an aptitude test. Followed by a zoom meeting with one of the interviewers. Unfortunately, I didn't feel like I did well on the interview
