I applied for a different position but was called for an interview for an embedded software engineer role. I passed their home test (2.5 hours) and was then called in for an onsite interview. I think they just use the home test to verify if you can

After passing the skill test (coding on computer), I received the interview from three people: my manager, my manager's manager, and a senior software engineer.

OA, and then an HR phone screen. After that is an online interview with the tech lead. They asked some questions about the OA and some questions about the resume. I lost track after that.
