It was Manager's round and he asked me only 2 questions related to android. One was like a requirement what he had done recently. I told him how I can achieve that but he wasn't agree with me because he had done with something else. Then he asked me how to implement about FCM push notifications. I told him how we implement. He wasn't even updated with Android and keep saying we use Alarm manager and Broadcast Receiver classes for FCM push notifications. I told him that we use Alarm manager and Broadcast Receiver for local notifications then he said "It means you have never implemented FCM push notifications" and when I asked him to give me your macBook for 15 minutes and I show you how to do that. Then he was like interview is finished. He was acting as a sweet person on face what he wasn't.
