AI & Technical question

How does programmatic advertising work?

Practice this question out loud. An AI interviewer asks it, follows up like a real interviewer would, and scores your answer. Type or speak.

What this question tests

Tests basic technical fluency in ad-tech, explaining the real-time auction mechanics behind automated ad buying and selling.

Define it plainly: programmatic advertising is the automated buying and selling of ad inventory through software rather than manual negotiation.
Explain the real-time bidding flow: a user loads a page, an ad request goes to an exchange, and multiple buyers bid in milliseconds before the page renders.
Name the key players: the supply-side platform representing publishers, the demand-side platform representing advertisers, and the ad exchange connecting them.
Note the targeting layer: bids are informed by user data, demographics, browsing history and context, which is why this space intersects heavily with privacy regulation.
Mention the practical stakes: this system underlies most of the open web's display and video ad revenue, including platforms like Twitch's ad inventory.

Correctly names the three core players, SSP, DSP and exchange, rather than a vague ads-happen-automatically description.
Explains the real-time bidding auction mechanic specifically, the technical core of the question.
Connects the answer to the practical, business-relevant stakes, like privacy regulation's effect on targeting data.

Giving only a surface-level answer like ads are shown automatically without explaining the auction mechanism.
Omitting the roles of SSPs, DSPs and exchanges entirely.
