Data Engineering - Technical Interview

🎯 Focus: Judge how strong you are technically and how confidently you think under pressure.

Topics covered

Assessing SQL strength, analytical thinking, and coding skills
Problem-solving & DSA to evaluate logic-building capability
Technical depth check on core data engineering tech stack ( like Spark, NoSQL, Databricks, Kafka, Snowflake, Airflow, Azure/AWS/GCP )
Scenario-based debugging to test real-world mindset
Feedback on gaps, preparation roadmap & improvement areas

Coming Soon

✅ This plan includes one 60-minute mock interview session

Data Engineering - Design Interview

🎯 Focus: Judge if you think like a real-world Data Engineer who can design systems, not just code them.

Topics covered

Evaluating your ability to design scalable data pipelines
Testing warehouse modelling & data architecture thinking
Judging end-to-end thought process (latency, cost, SLAs, quality, governance)
Understanding how you pick right components and justify choices
Review of your thought clarity, trade-offs & design maturity

Coming Soon

✅ This plan includes one 60-minute mock interview session

AI / ML Engineer & Data Scientist – Junior Level (0–4 Years)

Focus: Evaluate your fundamentals plus your readiness to work with modern AI systems (LLMs & GenAI) at an implementation level.

Topics covered

Core ML fundamentals (regression, classification, clustering, evaluation metrics, bias–variance)
Statistics basics used in ML & data analysis
Data preprocessing, feature engineering & exploratory data analysis (EDA)
Hands-on skills in Python, Pandas, NumPy & SQL
Training, validating & interpreting machine learning models
Introductory deep learning concepts (neural networks, loss functions, embeddings)
Practical understanding of LLMs & GenAI basics (what LLMs are, prompts, tokenization, embeddings)
RAG fundamentals (why RAG is needed, high-level flow, basic vector search concepts)
Using tools and frameworks to build simple LLM-powered applications
Debugging ML & GenAI issues (hallucinations, poor retrieval, ineffective prompts)
Personalized feedback on concept gaps, projects & learning roadmap

Coming Soon

✅ This plan includes one 60-minute mock interview session

AI / ML Engineer & Data Scientist – Senior Level (5+ Years)

Focus: Judge whether you can design, scale, and own modern AI systems, not just train models.

Topics covered

End-to-end problem framing (business → data → ML/GenAI → impact)
Designing scalable ML & GenAI pipelines
Deep understanding of LLM-based system design
RAG system design & trade-offs (chunking strategy, embeddings, vector databases, retrieval vs generation balance)
Prompt engineering vs fine-tuning vs adapters — when and why to use each
Evaluation strategies for LLMs & GenAI systems
Handling latency, cost, observability & reliability in AI systems
Managing data drift, concept drift & continuous learning strategies
MLOps + LLMOps maturity (monitoring, versioning, rollback strategies)
Cloud & infrastructure choices for AI workloads
Stakeholder communication & justification of architecture decisions
Review of thought clarity, ownership mindset & system-level maturity

Coming Soon

✅ This plan includes one 60-minute mock interview session
