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. Then he asked me to show another project/codebase. 1 funny thing I have observed is, He suggested me to keep your all project codebase in the system to show the interviewer.
