Amazon visited my college and offered me SDET-I position. GeeksforGeeks helped a real lot in my interview preparation. Thank you very much GeeksforGeeks!

Here is my interview experience:

Round 1 (On-line Coding Round on HackerRank):
1. Given an array of sorted integers which represent box sizes and an integer representing an item size
    You have to find best fit box for the item (-1 in case of no box found)
  For example:
    Given 10,20,30,40,50,60,70 and 45
      You have to print 50
    Given 10,20,30,40,50,60,70 and 75
      You have to print -1
      Given 10,20,30,40,50,60,70 and 50
    You have to print 50

F2F 1:

1. Given an array of integers
you have to output sequence a1,a2,a3,a4,a5,a6,a7 such that a1a3a5a7
    For example:
    Given 10,20,30,40,50,60,70
      You have to print 10, 30, 20, 50, 40, 70, 60
At first, I gave answer using sorting. But my interviewer asked me to do this without sorting the input array, and I did it.
2. A simple question on Tree data structure which i don’t remember.
3. Questions related to my project.

F2F 2:

1. A matrix is given which is sorted row wise and column wise
You have to print the sorted order.
    For example:
       1 2 3 4 6 8
       2 3 3 4 7 8
       2 3 4 5 7 8
       2 3 4 5 8 8
       3 4 4 6 8 9
       4 5 5 7 8 9
    You have to print sorted order
2. Questions related to my project during my internship.

F2F 3:
1.What happens when we type
Relating to this the interviewer asked me every step in detail including all 7 layers of networks.
Protocols like: HTTP, HTTPS, DHCP, DNS, IMAP, POP, TCP, UDP etc. Their uses and differences.
2. Describe ACID property of a transaction (DBMS).

Bar Raiser(Telephonic):
1. Given a singly linked list, write a recursive method to reverse every 3 nodes in the list.
He asked me to inform if I have seen the question.
And I replied : Yes sir, it is the similar question I faced in coding round of Amazon-internship last year.
But he didn’t changed the question.
I solved it with a silly mistake which i corrected when mentioned.
2. Long discussion on my internship and about the projects I have worked on.
3. Tell about your criticism.
4. 3 weaknesses currently i am working.
