Pine Backend Software Developer interview questions

My interview process with Pine involved four stages. The first was a screening with the recruiter. The second was a technical interview, which included building a backend API in about an hour. The third stage was a Systems Design interview, which could be done in person or online. This stage was fair, given the backend focus, and the goal was to assess how well I could approach the problem from a high-level perspective, with a few deeper dives into specific areas. After the technical interview, I was told I performed exceptionally well. I reached out to the hiring manager for constructive feedback but didn’t receive a response. The final step was an interview with the leadership team, but unfortunately, I didn’t make it that far.
