After submitting my resume, a recruiter contacted me and conducted a phone screening. We walked through the next steps. I completed the online coding assessment, which was relatively easy.

After making it past that, I interviewed with the hiring manager. The next step is a panel interview, apparently, but I didn't make it that far.

The recruiter told me that the interview with the hiring manager was going to be behavioral, but it was actually entirely technical, which was frustrating and disorienting. The questions weren't hard, especially for someone with a strong understanding of OOP principles and error handling. It didn't feel like a senior-level interview at all -- more like a blend of entry-level SDE and SDET questions.

What's wrong with this automated test code?
