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? Why so? What is ANR? What is the most common way to getting rid of it? What are some diff ways to do bacground processing? why is it needed? What is a backstack? How does it work? Something related to Livedata and its work. Coding question : Given a 2D array (e.g. {{915, 1200}, {1145, 1430},{845, 1030}}) where we have start time and end time in int format, we need to return true if our meeting time doesnt overlap with those times false otherwise isMeetingPossible(array, 1200, 1400) -> true/false
