What is AI? — AI Technical Interview Questions & Answers

What is AI?

What is AI?

  • AI is a program that does a job people used to call “thinking”: sort spam, read a number plate, suggest the next song. It is not magic and it is not a person. You give it data and a goal. It learns a pattern or follows rules, then acts. A fresher should say that in one breath before any buzzword.
  • Narrow AI does one job well — Gmail spam, Google Maps traffic, a hospital scan helper. General AI that can do any human job does not exist in products today. Don’t say “AI is like a brain” and stop. Say: machine + data + goal + feedback.
  • Board: mails = ["win lottery", "lab at 4"]. A tiny filter flags lottery as spam. That is AI at freshman size: a rule or a model, not a robot with feelings. Companies hire people who can explain this without hype.
  • What is AI? — output: win lottery now → spam / lab meeting at 4 → ok / free prize click → spam. A rule on text — not a person.

Code Examples for What is AI?

Example

# Narrow AI: a tiny spam rule
mails = ["win lottery now", "lab meeting at 4", "free prize click"]
for m in mails:
    spam = "lottery" in m or "prize" in m
    print(m, "→", "spam" if spam else "ok")

What is AI? — output: win lottery now → spam / lab meeting at 4 → ok / free prize click → spam. A rule on text — not a person.
