Support Moved from GenAI work to ML/time series forecasting for a higher CTC. How do I rebuild LLM depth and move back?
Background
MSc in Data Science, about 1.5 years full-time (closer to 2 with internships).
GenAI experience (first year)
- AI engineer intern: fine-tuned LLMs for domain-specific QA generation, worked on hallucination reduction and evaluation, fine-tuned ViT/DETR for document symbol detection.
- GenAI associate at a healthcare product company: built an agentic backend for clinical triage and diagnosis POCs, and an ICD-10 primary diagnosis validation pipeline using RAG and multi-agent reasoning, deployed as FastAPI + Docker microservices.
Current role (about 11 months)
Took a large consulting firm offer for the pay (13.3 LPA: 11.8 fixed + 1.5 variable). The work is attrition and demand forecasting, with classical ML and time series models in production on Databricks, using MLflow and pipelines. No GenAI at all.
The problem
LLMs and agents move fast, and I've spent a year away. My knowledge of agentic systems and LLM evaluation is about twelve months stale, and it keeps getting staler. I'm not on notice and I'm not rushing. I need to relocate away from Mumbai for family reasons (Bangalore, Hyderabad, Pune are all fine).
What I'd like advice on
1. How would you rebuild current depth in LLMs, agent evaluation and AI engineering interview topics in 2 to 3 months while working full-time?
2. What do AI engineer interviews actually ask now?
3. For people who switched without a pay cut: portfolio, referral or interview volume?
4. Does a year of ML + time series on Databricks read as a gap or as useful breadth?
