What to expect in an SAP application engineer interview at google?Any experiences?

How did it go?

I've completed all the interviews over the past couple of months. 2 coding rounds - leetcode easy/medium level problems. 1 app design round - end to end app design, focus more on schema/apis/data base. 1 integration round - similar to the app design round, with more focus on data flow, migration, security. Finally, the googlyness round, which is a leadership/behavioral round. If you do fairly well in these, your 'packet' is sent to the hiring committee and you'll also have the manager team fit discussions.
