I interviewed for i2c Software Engineer and hit a very challenging technical deep-dive focused specifically on I2C protocol details.

Technical interview (I2C deep-dive) — I was asked to explain what I2C is and how it works, cover master–slave relationships, list key features, and discuss arbitration.
Protocol behavior questions — I had to explain clock stretching and how it’s implemented, plus the addressing scheme used in I2C.

Outcome: I wasn’t offered a role; the takeaway was that success required precise, low-level knowledge of the I2C protocol mechanics.
