HR Phone Screen: (Got back to me with in a week after the initial round)

• He asked in-depth questions from my resume, my interests and a couple of changes I would do to my project if I had more time. Asked how would I manage a server or what server architecture I would use being said that usage will drastically increase. Whether I had considered customer when developing the project

Onsite Interview (Scheduled 25 days after the HR call )
8:00 am - 12:00 pm, Four rounds, Informed one round will specifically be for design.
HR told me that, I will be evaluated on: Algorithm Design, Use of Data Structures, How easily I can convert my idea to code and designing skills(Defining functions when needed, Using Classes appropriately)

Round 1: [Two managers]
They were from different teams and said they don't know much about the team I am Interviewing for.

• 20-30 minutes: LP-based questions
• How would I design, to suggest friends in a messaging application.
  GIven list map of the ID of friends
  Input: List Map: [[1:2,3,4,5][2:6,7][3:6,9,2][4:12,6,7,9]] (Here user with ID 1 have Users with ID 2,3,4,5 as friends)
  Output: For 1 my suggestion list will be this [6,7,9]
  Explanation: I should return mutual friends of 1 who repeats more or equal to twice. Here when I count all mutual friends of 1 using another map, It looks like this {6:3,7:2,9:2}
  5 minutes: To clarify my doubts about Amazon

Round 2:
This is also with a manager from the same department but a different team.

• 20-25 minutes: LP-based questions
• Given a singly linked list. Flatten the linked list and sort. (Follow up: sort in place, no extra memory, Should do it in O(N log N))
  Input:
  5->4->1->5->9
  |
  3
  |
  2
  (Here 5 has two pointer, next(4) and down(3) and
  Output:
  1->2->3->4->5->5->9

Round 3: [Hiring Manager]

• 30 minutes: LP-based questions(Lot of follow up questions)

• Design Chess game. What will be your classes, relation between different classes, represent board, represent players, How will you begin the game?

  I didn't perform well in this round :( ,

Round 4: [Senior Developer]

• 20 minutes: LP question
• https://leetcode.com/problems/course-schedule-ii/
  Given a list of processes and their dependencies on other processes, Return order of the process to be executed in so that given all the processes will run
  Input: p1->p2,p3 (Here p1 is dependent on p2 and p3)
  p2->p5
  p3->p4
  p4->p5
  p5

Output: [p5,p4,p3,p1,p2] or [p5,p2,p4,p3,p1] (because p2 is only dependent on p5)

Interview accommodation, flight tickets, cab and food was provided by company
Overall it was a very good experience, Interviewers are welcoming to discuss, explain, clarify and help

Disclaimer: For behavioral questions mostly people think It is enough if they prepare a scenario justifying LP principle\s but remember the Interviewer gonna always ask a lot of follow up questions and they will be noting down every word you will say. So be prepared to answer all possible follow up questions(extensions).
