Interview Preparation Tips

Round: Test
Experience: Only a few students will get shortlisted who do all the questions correctly.

Round: Other Interview
Experience: First 4 rounds on day 1 and this are just to shortlist for more rounds on some other day.
Tips: They will focus on almost all the concepts of computer science.You need to practice a lot and start it right now. Should be easy if you have prepared well enough. Use your holidays to start preparing for placements.

General Tips: Sooner you start, better your placement will be as lack of practice & last day study works only for exams but never for interviews. You'll get enough time to prepare for interviews once you get shortlisted. Focus on it even if you are placed already.
Skill Tips: They will focus on almost all the concepts of computer science.
Skills: C , Aptitude

I was interviewed in Dec 2016.

Interview Preparation Tips

Round: Technical Interview
Experience: On-site interview (5 hours).

4 back-to-back 45-minute coding interviews, followed by a design interview, with a lunch break with a Googler in the middle.

The first coding interview was a set of (surprisingly) trivial (no algorithms needed) incremental coding questions.

The two next coding interviews were problems straight from the "Cracking the coding interview" book. Even though I divulged that I'd solved pretty much exactly the same problem before, they didn't give me an alternative problem and I quickly coded up a general and optimal solution for the problems. Follow-up in-depth questions were minimal and not hard.

The last coding question was a pure algorithm question related to search trees/tries. No coding required, spent the whole time reasoning about the most effective algorithm. This was a bit of a brain twister.

The design question was related to high-level system design (not OO design) for storage and search in geographic data. Focus was effective search as well as scalability both in traffic and data volumes.

Tips: Read "Cracking the coding interview" or other similar literature. Solve all the problems and you should be good to go. If you solve a bunch of problems at HackerRank (or similar) as well, you'll have the added bonus of training on how to generalize the algorithms.

data structures, networks and operating systems to theory of computation
Duration: 45 minutes
Total Questions: 25

Round: Test
Experience: The second test contained 3 coding questions.
Duration: 45 minutes
Total Questions: 3

Round: HR Interview
Experience: After the written test, next day I appeared for 3 interviews.
They were checking if you can write code and also if you are aware of the practical issues faced while coding. In the final round they were testing if you could abstract out a real world
problem into code.
Tips: Overall I can say that you must hope for the best and prepare for the
worst. So make sure that you are prepared on all counts. You never know what might go wrong.

I applied via Campus Placement

Interview Questionnaire 

4 Questions

  • Q1. Boundary traversal of a tree
  • Ans. 

    Boundary traversal of a tree is the process of visiting the nodes on the boundary of a tree in a specific order.

    • The boundary traversal can be done in three steps: left boundary, leaf nodes, and right boundary.

    • For the left boundary, start from the root and traverse down the left side of the tree until reaching a leaf node.

    • For the leaf nodes, perform an inorder traversal to visit all the leaf nodes of the tree.

    • For the ri...

  • Q2. Find the nearest greater value of a given value in a BST
  • Ans. 

    Find the nearest greater value of a given value in a Binary Search Tree (BST).

    • Start from the root node and compare the given value with the current node's value.

    • If the given value is less than the current node's value, move to the left subtree.

    • If the given value is greater than the current node's value, move to the right subtree.

    • Keep track of the closest greater value encountered while traversing the tree.

    • Return the cl

  • Ans. 

    Given an infinite staircase with a broken kth step, find the maximum height we can reach in n rounds of jumping i steps.

    • We can start by jumping the maximum number of steps in each round until we reach the broken step.

    • After reaching the broken step, we can discard the i steps that would land us on the broken step and jump the remaining steps.

    • We can continue this pattern until we reach the maximum height we can reach wit

  • Answered by AI
  • Q4. Height h was given and form a binary tree of height h and start combining bottom nodes to form a cone like structure

Interview Preparation Tips

Round: Test
Experience: there were 20 MCQ which were on ds , networks and basic coding followed by 2 coding questions.
1) print all the distinct substrings of a given string in lexicographical order
2) find the max i-j value in the given array of 0's and 1's such that there are equal number of zeros and ones, where i is the starting index and j is the ending index of the array.
Tips: make sure that you pass atleast half the test cases for both the question.
Duration: 90 minutes
Total Questions: 22

Round: Technical Interview
Experience: 1) i printed left view then leaves and right view using three level order traversals . he asked me to use one traversal only, then i told him the approach and wrote the working code.
2) told him the approach and coded it.
Tips: look at corner cases properly. the interviewers were friendly, so i felt relaxed.

Round: Technical Interview
Experience: 1) i told him a recursive O(2^n) solution, optimised it to O(n^2). he told me to optimise further. Then i finally came up with O(n) solution after 5 min and he was satisfied . i coded it. he was satisfied finally :D .
2) came up with the approach immediately and coded it. he was satisfied.
Tips: he was very particular about corner cases and he checked the code througly tested it on some cases to ensure it was working.

General Tips: be cool. interviewers were friendly. tell them what you are thinking and be clear with the question before answering to avoid wasteage of time.
Skill Tips: solve problems from codechef, spoj and codeforces. solve interview questions from geeksforgeeks and careercup.
Skills: the way you think, coding skills and knowledge on data structures.
Duration: 3
College Name: IIT Roorkee
Motivation: some good seniors got intern, so i was inspired.
Funny Moments: on the interview day a person came into the conference room to call me for interview, i didnt thought he was interviewer. he was very simple, but intelligent and at last i felt like asking him to ask me one more coding question as it was fun solving questions infront of him, but i didnt do that as i was frightened if i would not be able to answer it would be a negative remark :P .
