What this question tests
Basic technical fluency in ad tech, specifically how ads get inserted into video streams.
How to approach it
- Define client side: the player app itself requests and stitches ads at playback time.
- Define server side, often called SSAI: a server merges ad and content into one stream before it reaches the device.
- Compare ad blocking resistance: server side is much harder to block since ads look like content.
- Compare latency and buffering: client side risks a visible seam or buffering at ad breaks, server side is seamless.
- Compare targeting flexibility and reporting: client side can personalize more easily but is less robust.
- State a recommendation, SSAI for live sports or premium video where ad blocking and seamlessness matter most.
What a strong answer includes
- Names FreeWheel and similar vendors as SSAI providers, grounded in common industry knowledge.
- Explains the tradeoff clearly: server side trades some targeting agility for reliability and fill rate.
- Mentions manifest manipulation as the mechanism server side uses to splice ads.
Common mistakes
- Confusing the two directions or defining them backwards.
- No mention of ad blocking as a key driver of the choice.
- Treating it as a pure technical question with no business tradeoff.
Likely follow-up questions
- Why would a live sports platform prefer server side integration?
- How would you measure ad viewability in each approach?
