The recruiter was responsive and professional. After the recruiter call to discuss roles, there was a technical screen. The interviewer was not paying attention for half of the interview and also seemed perturbed with answering questions, such as valid inputs. This was extremely unusual, as these interviews typically focus on communication, but this interviewer was unwilling to communicate. They even, at one point, went on mute to talk to their roommate in the background and joke around in the middle of the interview. It was pretty clear that they had no interest in putting effort into the interview, so it didn't matter that I solved the problem.
