Typical job interviews questions, but here are some notables ones : - What is the thing that you are the most proud of in your previous experiences ? - Have you ever made one big mistake in your previous experiences ? What did you learn from it ? - Are you okay with having less responsibilities than in your current job ?
Q.1 : Deeply OOPS concept Q.2 : Fragment add() and Replace() Q.3 : Basic Sqlite Q.4 : String vs StringBuffer Q.5 : Intent Service vs Service Q.6 : Activity life cycle Practical : Api call and filter dynamically recyclerview (selection by spinner)
Que experiencia tengo como desarrollador Android?
What is ANR and how to avoid it?
There was a coding question.
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. JAVA: equals & hashcode, Arraylist & LInkedList, Threads, Lock, Object (wait, notify), Synchronization, Checked & Unchecked Exception, How to create unchecked exception, collections, Design Patterns. O(n): 1. ArrayList & LinkedList(Insert, add, delete, access). 2. Traverse whole items in ArrayList & LinkedList which is faster? both are O(n), O(n) but ArrayList would be faster. 4. Code Pair (HackerRank) By Senior Developer(Around 5-8 years) Opinion on why RecyclerView is lagging(scrolls slowly). Q. Write a function to reverse the integer. - what if no is negative - what if reversed no is no longer in range of integer return 0 (check with Integer.MAX_VALUE & Integer.MIN_VALUE)
Difference between serialization and parcelable
Write/pseudocode a unit test for the project
