Garmin Embedded Software Engineer interview questions

I was contacted by a recruiter to apply on LinkedIn to apply for an embedded software role on their watch team. I was immediately told my years of experience from doing research as part of my MS would count which is usually a red flag for me. The recruiter convinced me to interview for the next role which I accepted out of curiosity. The next interview was a technical one which consisted of a round of questions regarding my resume and another with coding in C++. During the first portion, they oddly focused on a part of resume that was most pertinent to what they were doing at the time. I thought this was odd as most other interviews I've had the team tries to get a sense of you holistically and not just one portion of your career. The last bit was a coding challenge in C++ which I honestly struggled with a little as I haven't written in that language in a very long time, something I made apparent in each interview I had with Garmin. As this role was supposed to be more signal focused, I received very few questions related to this area. The senior engineer was kind enough to explain to me that the role was more towards debugging and maintaining code rather than developing. I was happy to walk after this discussion. For those in medical device already and are interested, the culture is not the same to the one you would be leaving.
