Excerpts from Interview #2:
(A CSE student with profile as 8.47 CGPA and having 88.8% in 12th and 92.8% in 10th. Offering summer internship)
Technical interview I:
  • Given a linked list, reverse K nodes in it.
  • Search for an element in an array which has elements who’s values are first increasing and then decreasing. (Use modified binary search)
  • Find the second largest element in an array.
  • Given a sorted array which can have repeated elements, find the occurrence of an element. (Most optimal solution is O(log n) – Using binary search to find start and end occurrence)

Technical interview I:
  • Given in face book find an efficient way to find the mutual friends between you and one of your given friends. Hint: hashing, dictionary data structure implementation
  • For two very long numbers given, find the product of these numbers in an efficient way. Hint: using binary multiplication effectively.
  • Given a number n, find the number just greater than n using same digits as that of n.
  • Given n coins for two players playing a game. Each player picks coins from the given n coins in such a way that he can pick 1 to 5 coins in one turn and the game continues for both the players. The player who picks the last coin looses the game. You have to tell that for given n coins who loses the game?

Excerpts from Interview #5:
(A CSE student with 9.19 CGPA and having 94.6% in 12th and 93.4% in 10th. Offering job profile as Software Developer.)
Technical interview I:
  • He asked me the worst case complexities of Quick sort and Merge sort.
  • Given an array that contains post-order traversal of a binary tree. Can you construct a single tree? I said no. Then he asked if i can make a binary search tree from the array to which i said yes. Then after discussing the approach, he asked to write the code.
  • Then he asked me to write the code for level-order traversal of a tree. Also asked me to calculate the complexity of the code.
  • Given a linked list placed in memory, what problems can arise if simultaneous operations are performed on the list. From here he started asking about threads because the answer was related to it.
