First Step is the online coding test at HackerRank.
Second Step is the Technical Interview.
Third step is the experience round.
Fourth step is the executive round .
Fifth is the final HR round.
Interview questions [1]
Question 1
In the coding test, 2 questions were based on data structures and algorithms and 1 question on data science.
In the technical interview, questions were asked on machine learning and deep learning algorithms and some basic statistics. Level of questions asked were between average and good.
In the experience round questions were asked regarding the previous work experience.
In the executive round basically they will talk to you about your projects and some basic technical questions.
Final HR round will be about your personality.
Thank you for taking the time to share a detailed account of your experience interviewing with Fractal. Congratulations on your offer and decision to join Fractal. We are so happy to have you on board.

Other Data Scientist Interview Reviews for Fractal
I attended a one-hour AI/ML interview focused on Machine Learning fundamentals and practical applications. The discussion covered ML algorithms, model selection strategies, evaluation metrics, feature engineering, optimization techniques, and deployment challenges. The interview included conceptual, problem-solving, and scenario-based questions to assess both theoretical understanding and practical experience in AI/ML.
Interview questions [1]
Question 1
The interview was primarily focused on Generative AI concepts and their practical applications. Questions covered Large Language Models (LLMs), prompt engineering, Retrieval-Augmented Generation (RAG), vector databases, embeddings, fine-tuning techniques, and AI agent frameworks. The interviewer also asked scenario-based questions on designing GenAI solutions, selecting appropriate architectures for different use cases, handling hallucinations, evaluating model performance, and addressing scalability, security, and deployment challenges. Additionally, there were discussions around real-world implementation of GenAI applications, model optimization, and best practices for building production-ready AI systems.
Good and Short interview process
3 round of interview
1 take home assignment
1 round technical
1 round HR
each interview last 30min
Interviewer were supportive and helping
Whole interview take 1 week
Mildly challenging and nice. I would probably reduce number of rounds, i had 4 of them. The first two were technical and third one was managerial. The last round was done for cultural fit.
