Hello there,
Thanks for reaching out to us. I'm afraid that I can only respond to you in the English language.
Please note that we are only able to handle queries specific to the Mobile Ads SDK implementation and feel free to correct us if we misunderstood your query. Interstitial ads are full-screen video ads which are shown to the users at natural transition points in the flow of the app such as between activities or during the pause between levels in a game. We will not be able to comment on any specific implementation. However, please take a look at the below articles to implement Interstitial ads as per you requirement.
