AI refers to the simulation of human intelligence in machines programmed to think, reason, learn, and make decisions. It includes areas like machine learning, natural language processing (NLP), robotics, and vision.
AI Interview Questions
1. What is Artificial Intelligence (AI)?
2. What are the main types of AI?
- Narrow AI (Weak AI): Performs a specific task (e.g., Google Assistant).
- General AI (Strong AI): Human-level cognition (not yet achieved).
- Superintelligent AI: Hypothetical AI surpassing human intelligence.
3. What is the Turing Test?
Proposed by Alan Turing to assess a machine’s ability to exhibit intelligent behavior indistinguishable from that of a human.
4. Explain the difference between symbolic AI and connectionist AI.
- Symbolic AI: Uses rules and logic (e.g., expert systems).
- Connectionist AI: Based on neural networks and learning from data (e.g., deep learning).
5. What is NLP and how is it used in AI?
NLP enables machines to understand, interpret, and generate human language. Applications: chatbots, translation, sentiment analysis, summarization.
6. What are LLMs (Large Language Models)?
LLMs like GPT, LLaMA, and Claude are AI models trained on massive text data to understand and generate human-like text. Used in chatbots, code generation, and writing assistants.
7. What is prompt engineering?
The practice of designing effective prompts to guide LLMs like GPT to give accurate, desired responses.
8. What is the difference between stemming and lemmatization?
- Stemming: Trims words to their root (e.g., "running" → "run").
- Lemmatization: Considers the word’s meaning and reduces it to its base form ("better" → "good").
9. How does AI enable computer vision?
AI (especially deep learning with CNNs) helps machines recognize objects, faces, gestures, and scenes from images or videos.
10. What is SLAM in robotics?
SLAM (Simultaneous Localization and Mapping) helps robots map their environment while tracking their own location in real time.
11. What is the difference between AI and Robotics?
Robotics involves building machines; AI gives them “brains” to make decisions. Not all robots are AI-powered, and not all AI is used in robots.
12. What is an expert system in AI?
An AI program that mimics human decision-making using a knowledge base and inference engine (e.g., MYCIN for medical diagnosis).
13. What is fuzzy logic?
A form of logic that handles reasoning with uncertain or imprecise information, useful in thermostats, automatic brakes, etc.
14. What are ontologies in AI?
Ontologies define structured relationships between concepts in a domain, often used in knowledge graphs and semantic web AI.
15. What are the key ethical concerns in AI?
- Bias and fairness
- Privacy
- AI misuse (e.g., deepfakes)
- Transparency and explainability
- Job displacement
16. What is Explainable AI (XAI)?
AI systems that provide human-understandable justifications for their outputs — critical in high-stakes areas like healthcare or law.
17. What is AI alignment?
Ensuring AI systems’ goals and actions align with human values and intent, especially important in autonomous or general AI.
18. What are foundation models in AI?
Large pre-trained models like GPT, PaLM, and DALL·E that serve as general-purpose models and can be fine-tuned for various tasks.
19. Name real-world applications of AI.
- Self-driving cars
- AI in finance (fraud detection)
- AI in healthcare (diagnostics, drug discovery)
- Smart assistants (Siri, Alexa)
- Recommendation systems (Netflix, Amazon)
20. How is AI regulated globally?
Governments and organizations (like EU’s AI Act, OECD, and U.S. Executive Orders) are pushing for responsible AI with standards around safety, bias, and transparency.
