Behavioral Technical
The interview was just one round, and it had both HR and technical parts. They started by asking me some HR questions about my background, what I want to do in my career, and why I applied here. Then, the technical part was all about my projects, especially the one where I built a resume screening system using an LLM. I had to talk about the system's architecture, how I picked the model, how I designed the prompts, what metrics I used to evaluate it, and how I deployed it. They also wanted to see if I understood Large Language Models well, the difficulties of putting them into practice, and if I could solve problems. It felt pretty structured and was a decent challenge overall.
Confirmed questions2 questions
- Could you explain the working principles of Large Language Models and how you incorporated an LLM into your resume screening project, including your methods for prompt engineering, addressing bias, ensuring scalability, and assessing the accuracy of candidate-job matching?
- Can you tell me about how Large Language Models function and how you integrated an LLM into your resume screening project, specifically regarding prompt engineering, bias mitigation, scalability, and evaluating the accuracy of candidate-job matching?

Technical Behavioral
There were two video calls for the interviews. The first one was a technical interview that lasted 45 minutes, where they checked my technical abilities, problem-solving skills, and past experience. The second one was a 20-minute behavioral interview, focusing on how I communicate, work in a team, and if I'm a good cultural fit.

Technical Coding Behavioral
So the TCS Ninja interview process, you know, it starts with this online test called TCS NQT. It has three parts: numerical ability, verbal ability, and logical reasoning. It's about 190 minutes long and the questions are kinda in the middle difficulty-wise. Then, after that, there are the interview rounds, which are held at the college. These include a TR (Technical Round) + MR (Managerial Round) + HR round. They ask stuff about your resume and projects, basic OOPs, DSA, DBMS, and SQL. They also give you simple coding problems like palindrome or swapping numbers. And some typical HR questions like 'Tell me about yourself', 'Why TCS?', 'Strengths', 'Relocation', and 'Team experience'.
