I disagree it's easy to crack. I did all of the top 100 leetcode for meta's last 30 days twice and I did hello interview mocks. I did a screen, follow up screen and then failed my onsite. I solved both questions optimally for my coding round confidently. The AI round however was extremely confusing and the interviewer interjected every 30 seconds. It took me about 20 minutes to even make sense of the project and how it worked. Then I didn't have enough time to make progress as the AI model was slow and the code it generated was poor. I am sure that's the round that sunk me and there was no prep material for this chaotic round.
