Mobile Programming Senior Android Developer interview questions

Firstly I will tell you do not join this company if they are not provide actual offer letter along with do not accept provisional offer letter because they will play game with you even they do not reply on mail. Same things happend with me and my recruiting procedure was very poor even they depend on director reply and unfortunately director is very busy, Sandeep was the hr person and do not except any thing from his even after commitment they not provide you joining. I do not know why but it happened with one of my friend and me as well I think they always looking alternate of you who works with @ minimum LPA apart from this Interview went very well, even I got selected here they mainly asked regarding latest of android with conceptual questions they asked from jetpack component, Kotlin, DS etc, the timing was about 40 minutes.
