CircleCI Senior SRE - Infrastructure interview questions

The interview process with the recruiter and the hiring manager was great, no issues there. Was told I would have a 3rd party do the technical *Karat* and that it would be systems and infrastructure related and not Software Engineer related questions as I am not a SWE, I am SRE Infrastructure. Karat interview proceeded to ask nothing but SWE questions and had a code portion geared towards Sr SWE. I discontinued from the Karat portion and notified the recruiter of my dissatisfaction and felt like I wasted time preparing.
