Worst Experience till now, In Interview Interviewer, doesn't know about A of Android. He asked me to "show me your project, I know Java will judge you on behalf of the codebase". but unfortunately, I have written a sample app in Kotlin.

Android: (first 5 mins) => 5,6 questions (Answered all of them, interviewer was happy) (Performance : 9/10) Couple of basic Android fundamental questions that I dont remember How would you update few items that have been changed on the recyclerview?
