I applied through university. The process took 3 months. I interviewed at LTIMindtree in Mar 2025
Interview
I was invited to the LTI Mindtree Kolkata office for an in-person interview. The process was structured into two main rounds:
1. Automated Assessment (iBot)
The first round was an automated assessment conducted via their internal platform (iBot). The test included basic multiple-choice and scenario-based questions, primarily focused on Generative AI concepts, including foundational understanding and recent advancements.
2. Technical Interview (In-person)
The in-person interview consisted of the following segments:
Resume-based Discussion:
The interviewer started by asking questions from my resume. A major focus was on my Generative AI projects, for which I was asked to explain the architecture, technologies used, and the real-world impact or applicability.
Core Machine Learning & Python:
I was then asked some basic ML questions like algorithm selection, model evaluation, overfitting/underfitting concepts, etc.
Python questions were mostly centered around logic, functions, and basic syntax – nothing too advanced.
Design-based Scenario:
One interesting part was a design question where I was asked:
"How would you design an SQL bot that can take human language as input and return database query results?"

Question 1
How would you design an SQL bot that can take human language as input and return database query results?
I applied through a recruiter. I interviewed at LTIMindtree
Interview
The interview process consisted of a total of three rounds. The first round was a technical interview focused on core technical skills and problem-solving abilities. The second round included both technical and managerial discussions. The final round was an HR interview covering general discussions, company policies, and salary-related details.
I applied online. I interviewed at LTIMindtree in Oct 2025
Interview
Interview Process was smooth. HR calls and asks for details and then Technical round happens with LTI mindtree client.If we clear this offer then we get offer. Questions are around ML, AI, NLP techniques , focuses more on projects we worked on.
Interview questions [1]
Question 1
1. Give brief about yourself.
2. Explain any project you have worked on based on ML,AI,NLP.
3. Did you face any hallucinations? How did you handle them?
4. How did you get the accuracy? Human evaluation?
5. What is self attention in transformer model?
6. Difference between stemming and lemmatization in NLP?
7. Named entity recognition?
8. What is part-of-speech tagging?
9. Any ML project, classification?
10. How do we decide root node for decision tree?
11. Imbalanced Dataset? How is it handled?
12. TFID vectorizer ? how does it work?
13. Deep Learning algorithm
14. what is vanishing gradient issue in DL?
15. Pooling or filters in DL?
16. Topic modeling in NLP.
4 people panel asked questions regarding machine learning deep learning transformers models a little about Gen Ai. Checking deep knowledge around all topics. The question are hard but can be cleared if someone have deep knowledge the model and why certain situation arise and what to do in that kind of situations
