Agoda interview questions

I had 2 rounds of online technical interviews, 2 sessions for each round, and 1 hour for each session. All of the interviews are focused on problem-solving using data structure and algorithms. I performed quite well in the first 3 sessions, had great conversations, technical problems were solved optimally. In the last session, I had an interview with a senior manager with a problem-solving type of question that its problem statement and example are stated very poorly. I struggled to understand the problem and the manager tried to explain the problem which was not that helpful. At last, I managed to solve the problem in time, asked the manager some questions, and end the interview session. A week went by, I got a rejection email. So, I asked for feedback and it turns out that I only failed the last interview because "my coding skill is not that good". In my opinion, this is weird. The company claims to be a "flat organization", where they "promote" employees to be involved in decision-making processes but when it comes to interviewing process, you still have one-above-all authority person to make a final decision even when the rest of the team says otherwise.

The recruiter round was only 15 minutes. She was mainly looking if a candidate has hands-on experience. technical interview which was scheduled within a week. The technical interview was about 1 hour.
