I don't understand the process. I scored 600/600, a perfect score, in the first round of the interview, which was a technical code round, yet I received feedback that I was not selected. I asked for more details about the feedback, and I was told that one code question was fine, but the second one I solved using brute force. If the system designed by the company and their hidden test cases accept that solution, then what else do you want a candidate to perform within that limited time? However, I provided another solution verbally, but I was still not selected.

First round:

Two coding questions.
