Groupon Android Developer - New Grad interview questions

Pretty lame. The recruiter was really nice. The technical interview was nice as well but just read from a script and barely at that. I have a handful of Android projects, 8 months of interning with Disney, and the Google Associate Android Developer certificate and the only question related to Android that I was asked was have you used RxJava and have what would you use for taking work off UI thread. Then went right into a recursive search type question. I understand companies like to use these basic CS questions because.. idk why.. lazy? In my 3 years of studying and building Android apps I have not once write a recursive search on device. Not saying I can not do so, but its been a couple years..
