How would you resolve a disagreement with a colleague?

"I got in through a referral, so I didn't have a recruiter screen and went straight into interviews. I applied around the end of September, didn't hear back until mid-November, then did two 45-minute virtual rounds in December: one technical and one googliness/behavioral. I heard back within the week that I passed, then had about another month to prep before the onsite in mid-January, which was just two more 45-minute technical interviews. The coding questions felt more custom than straight LeetCode, and the main thing Google seemed to care about was how I clarified the problem, communicated my thinking, and reasoned my way to a solution. I made it through the full loop but got rejected, and the timing was all over the place because the first feedback came quickly while the final decision took about three weeks."

"I had a long process with a recruiter screen, then a PM aptitude screen, then a full onsite loop for a PM leadership role managing PMs at roughly an L7-equivalent level. I put more than 100 hours into prep because this is absolutely not a night-before kind of interview, and I actually felt pretty strong across the first several rounds. The loop covered people management, cross-functional influence, execution and metrics, operating, project retro, and product sense, and the interviewer variance was real because some people would lightly guide while others gave me nothing. I got rejected, and I'm pretty sure the miss was the metrics depth in my last execution-style round, plus not going deep enough on secondary metrics in product sense."
