01

Understand the role

What matters most

  • Python Proficiency for GenAI

    The role requires strong Python skills specifically applied to Generative AI use-cases. You must demonstrate the ability to write clean, functional code that interacts with AI libraries and frameworks to solve practical business problems.

  • Application of AI/ML Algorithms

    You are expected to translate theoretical knowledge of AI/ML algorithms into actionable solutions. This involves understanding how to select, implement, and support models that address specific business requirements.

  • LLM Integration and Development

    A core priority is working with Large Language Model (LLM) applications. You should be prepared to discuss your experience or projects involving LLM-based technologies and how they are integrated into broader software applications.

Likely challenges to think through

  • Bridging Academic Theory to Enterprise Solutions

    As a fresher role, the primary challenge is moving from academic or self-initiated projects to enterprise-grade development. Prepare by articulating how your projects handled scalability, data quality, or real-world constraints, rather than just model performance.

  • Rapid Evolution of GenAI Technologies

    The GenAI field changes quickly, and you may be tested on your ability to learn new frameworks or tools on the fly. Demonstrate your adaptability by explaining how you stay updated with the latest research or documentation in the AI/ML space.
