American Express AI/ML Engineer interview questions

It was 2 rounds of interviews, One virtual and another on-site. The virtual was more of me talking about my personal project in GenAI. I was meant to do a leetcode style question at the end but since the interviewer saw all my codes from my project he did ask me to code. The final round was on-site and I got grilled for 1hr 30min straight, I was asked about the foundations of LLMs, their architecture, fine-tuning etc. From the feedback I got, I had not drawbacks but they did go with internal candidates since they know how RASA works for their chatbots.
