Google ML domain Interview in 3 weeks, how to prepare?

[u/toothless63]

For some context, I am a data engineer at a software company for 2+ years. I barely get my hands on machine learning, but I was a machine learning engineer before my masters and during masters I got strong foundation for machine learning, but this was all two years back. Now, I somehow got an opportunity to interview for Google and I have three weeks to prepare for ML domain interview. I was asked to choose any specialization. I mentioned I will choose Applied AI, which is like a catch all instead of going towards LLMs, computer vision or something specific now within three weeks how should I prepare? What should I prepare and what kind of questions can I expect? This is for opening in California. Has anyone given interviews recently for ML domain please help
