What is Artificial Intelligence?
Artificial Intelligence (AI) is a branch of computer science that aims to create systems capable of performing tasks that normally require human intelligence, such as visual perception, speech recognition, decision-making, and language translation.
What are the different types of AI?
AI can be categorized into three types: Narrow AI (designed for specific tasks), General AI (can perform any intellectual task like a human), and Super AI (surpasses human intelligence).
What is machine learning?
Machine learning is a subset of AI that enables systems to learn and improve from experience without being explicitly programmed, by using algorithms to analyze data, learn from it, and make predictions or decisions.
What is deep learning?
What is the difference between AI and ML?
What is Natural Language Processing (NLP)?
What is computer vision?

Technical Interview Mastery Blueprint
Proven methodologies and frameworks to succeed in technical and architecture rounds.
1. The Engineering STAR Technique
When responding to architectural or situational questions, structure your answer using Situation, Technical Constraint, Action, and Measurable Result. Rather than jumping straight to syntax, articulate the business problem, why certain patterns (e.g. caching, queuing, immutability) were selected over alternatives, and what latency or throughput improvements were achieved.
2. Defending Architectural Trade-Offs
Senior interviewers evaluate how you weigh trade-offs. Always explain why you chose an approach: e.g., memory overhead vs CPU cycle speed, consistency vs availability (CAP theorem), or normalized schemas vs denormalized fast reads. Stating the drawbacks of your own proposal demonstrates maturity and production experience.
3. Clean Code & Edge-Case Proactivity
In live-coding rounds, communicate your thinking aloud before typing. State edge cases explicitly: null or undefined inputs, extreme boundary values, concurrency races, and network timeouts. Writing modular, well-named functions with deterministic unit tests separates junior candidates from staff-level engineers.
4. Antipatterns to Avoid
Avoid reciting memorized definitions without practical context. Never dismiss non-functional requirements such as security (CSRF, injection, token rotation), observability (logging, metrics), and accessibility (ARIA, semantic standards). Always ask clarifying scope questions before writing complex implementations.
