My girlfriend interviewed there 1.5 years ago for same position, interview was pretty standard revolving around coding and algorithm questions. About 70% was C or C++ programming also some Python, a few questions just touching the basics of SPI to CAN, TCP/IP, OS, computer architecture and some basic knowledge of electrical engineering. If you have any experience with RTOS implementations (QNX, AUTOSAR...) that'll likely be a big plus, my girlfriend didn't have this but they asked for it during the interview. If you pass phone interview they'll invite you onsite that's again a coding interview and they'll be hugely focused on whether or not you're a culture fit, my girlfriend found this pretty annoying and didn't like the culture, she got an offer but turned it down, decent money though.
Good luck!
