I met with hiring manager and was asked for a totally irrelevant threat modeling of irrelevant asset which is not a web app or a mobile app or any type of network architecture.

HR contacted me for Product Security Engineer position. After our initial discussion, a technical interview was scheduled. HR Rep called with in couple days to let me know the feedback and also about the next steps. Onsite interview was scheduled according to the availability. Final interview had total 5 rounds including lunch with hiring manager. Felt comfortable talking with all the interviewers. The panel consisted of engineers from Infrastructure Security, Software Development and Product security. After the interview was done, heard back from the HR Rep in couple days. Competitive salary package and benefits.
