Core Programmatic Advertising Interview Questions
1. What is Programmatic Advertising?
A strong answer should explain that programmatic advertising is the automated buying and selling of digital advertising inventory using software platforms instead of manual negotiations.
Mention important components:
- Automation
- Real-time bidding
- Audience targeting
- Data-driven optimization
- AI-powered bidding
Recruiters often expect candidates to explain both the technology and the business benefits.

One of the most common interview questions.
DSP (Demand Side Platform)
Used by advertisers to purchase ad inventory.
Functions include:

The process:
- User visits webpage.

- DSP evaluates user data.
- Highest bid wins.
- Advertisement is displayed.
This process usually occurs in less than 200 milliseconds.

It enables automated buying and selling of advertising inventory while facilitating auctions between multiple DSPs and SSPs.
Examples include major industry exchanges that support billions of ad impressions daily.
