They were all about me coding. I felt like I had the same interview 3 times in a row, where they all focused on me creating a small app from scratch, and talk about architecture.

Que experiencia tengo como desarrollador Android?
The recruiter asked me some questions about myself and my professional background (experience, technologies, etc.).
The second technical interview was one hour of live coding where the interviewer described 2 non-Android related problems and I had to solve them with algorithms and data structures. This interviewer was a lot nicer than the first one, who in my opinion was quite stone faced.
1st Round by Recruiter: 3 sets of questions. 1. Java - Equals & Hashcode, Arraylist & LinkedList, Threads, Collections. 2. Android - Activity lifecycle, Async Task, RecyclerView, View & ViewGroup lifecycle, Fragments. 3. Data Structure and Algorithms O(n) - Arraylist & linkedlist, HashMap - (insert, delete, access & add). 2. Round HackerRank Test: 1-5 MCQ (Java, Android & O(n)): - series of lifecycle events moving from Activity A to B. - View lifecycle on "requestLayout" & on "invalidate" - FInd time complexity of given code snippet. 6. Check balanced braces. 7. In Unsorted array find unique pair where sum of these pair is K. 8. Problem on graph subcomponents.(Zombie Cluster). 3. Round By Android Developer(mostly 2-4 years exp.) Android/Java Theory & O(n) Android: Activity LifeCycle, View LifeCycle, Opinion on why RecyclerView is lagging(scrolls slowly), Async Task, MVP, Service.
