Here are the most commonly searched roles for interview reports -
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 e.g. valid inputs, etc. This was extremely unusual since 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.

Interview
The interview process was well organized and flowed smoothly. However, it had quite a few stages, starting with an HR interview to assess my background and skills, followed by a technical interview that included a live coding exercise and several in-depth technical questions. Overall, it was a thorough process that effectively evaluated both technical ability and problem-solving skills.
Interviewer had a particular solution in mind that took a different approach from my own. My solution was algorithmically correct but not one that they were familiar with and preferred a non-closed form solution.
