Walk through resume, and a LLM related take-home task, need to be familiar with NLP and LLMs. Standard quant interview questions, and you need to complete the task well and be able to walk through it.

It was a very nice experience - actually better than most other places I interviewed. They sent some academic research papers for review and then disucussed details about the paper - mostly how well I could understand the key concepts and whether I could find out the key assumptions and possible flaws in the assumptions.
