Tell me about a time when you used data to reach a conclusion.

Situation- We found that the ad consumption for users watching our streaming services solution dropped from 60% to 40% for mobile platforms.

Task- My task was to understand the cause and propose a remediation to address the drop in ad consumption

Action- I used the five W approach

1) When does the customer stop watching video- as soon as the ad gets triggered but before the ad stops playing (80% of customers)

2) Why does the customer stop watching video- The ad never plays, it only spins and waits for loading( typically time to load is 5 secs)

3) Why does the ad never load-As there is a client side ad implementation, the app on the device has to call the ad server. The delay is due to devices that are at least 2 versions prior to the current version(60-70% of traffic)

4) What happens when ad does not load for a few secs- User waits for 5 secs and either trys to watch textual content or load some other video

5) What are the alternatives to address this 1) Switch over to Server side ad insertion or look for a technical alternative that avoids the device trying to stitch the ad

Resolution- The approach used was to create a memcached session to stitch the ad on behalf of the device that allowed for implementation of client side ad integration without significant delays in loading the ad
