Round 1 - Face to Face 

(1 Question)

Round duration - 30 minutes
Round difficulty - Easy

It was in the day time. I was asked the programming language of my choice. It was mostly focused on programming fundamentals. I was asked 2 questions based on Data Structures and Algorithms.

  • Q1. How can you detect a loop in a linked list?
  • Ans. 

    A loop in a linked list can be detected using Floyd's Cycle Detection Algorithm.

    • Use two pointers - slow and fast, where slow moves one step at a time and fast moves two steps at a time.

    • If there is a loop, the two pointers will eventually meet at some point within the loop.

    • To detect the start of the loop, reset one pointer to the head and move both pointers one step at a time until they meet again.

Round: Technical Interview
Experience: Technical on paper test questions:(dis was only for 12 among d 26 shortlisted ppl after apti...others directly had interviews)
5 wer selected in this test who wer nw sent for interviews
TECHNICAL INTERVIEW: (pls list the questions asked in all the rounds)
26 shortlisted after apti (14 directly for interviews & 12 had one more technical on paper test...mentioned above)
der wer min 2 technical rounds for each of them...max were 5

- You are given course dependencies
A->B,C
B->D
C->A
D->nothing
The above dependencies mean...if you want to take course A...you should take courses B and C first....To take B,Course D must be taken first....D is an independent course and can be taken without any prior requirements.
Now you are told these dependencies.Come up with an appropriate data structure to represent these dependencies.Then write a code that finds out all the courses that the student can take up...in this case the student can first take course D because its independent.Now that course D has been taken he can next take up B as it depends on B alone...But the courses A and C can never be taken because they depend on each other...So here all the courses that can be taken are B and D.
After i wrote the code....he asked for all possible test cases
-Given an array of length N....It can be filled with nos. only from 1 to N....find which nos are repeated in the array
-Given pointers to two nodes in a binary tree....find their least common ancestor...each node has pointer to only the parent node...not the left and right child..
-In a binary tree(Not necessarily a BST)...suppose the weight of any node is defined as the product of the key value of the node and the level of the node(Root at level 1)...find the node with maximum weight in the binary tree
-A sorted array of size n is right circularly rotated k times and this rotated array is given to you as input...Find out the value of k in log n time .
-There are some processes running at time T....and there are processes running at time T+30.
You have to find out
1)Which processes died at time T+30,which were alive at time T
2)Which are the new processes at time T+30,which were not there at time T
3)Which are the processes that were there at time T and are still running at time T+30
What data structure will you use to represent the process lists and write code to find out the answers to the 3 questions above
-Given a binary search tree...and a target sum...starting at the root...which all paths add up to the target sum?...if there are multiple paths....return the path with least no. of nodes.

Interview Preparation Tips

Round: Test
Experience: The test was for two and half hours where 1 hour was for general aptitude, 1 hr was for coding aptitude(either on java or C or C++as you choose) and 1/2 an hour for two coding questions.

Round: Technical Interview
Experience: In technical round they asked puzzles, aptitude questions and basic C coding. I was asked to write the code for two questions(one was on sort and search) and was asked the logic of two questions.They asked basics of linked lists, stacks, queues. Infact they were not very interested in the syntax and were pressing on the logic

General Tips: Being a non software branch students is not at all a problem. The company took 4 interns where 3 were from core branches. The fact that we had to work in JAVA and most of us didn't know JAVA, the company only looks for aptitude and ability to learn. So if you don't know anything, tell frankly that you don't know that part, rather than guessing. Be thorough with what you know and confidentially answer all the questions.
Also do not be tensed and take things lightly, if the interviewer is joking. Be candid.
Skill Tips: Learn basics of coding from books . Aptitude can be done from sites likes geeks for geeks, etc. The level of aptitude is not very high and infact the coding aptitude is also theoretical and does not involve in depth knowledge.
