I went into the loop expecting something straightforward, but one of the coding/problem-solving rounds was derailed by unclear communication. The interviewer described one expected output and then, as we went, it turned out the target was different from what they initially communicated, and that ate up a noticeable chunk of time before I could even settle into the right approach.

The core problem itself felt like it belonged more to deep algorithmic optimization than what I associate with frontend work—specifically a variation of a knapsack-style challenge that turned into dynamic
