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: Case Study Interview
Experience: Q: Give me five steps to estimate the number of traffic lights in Bombay.
Me: I will divide the city into equidistant lines, both vertical and horizontal; sort of a mesh. Then I would take vertical and horizontal rectangles i.e. the rectangles which fall on length and breadth of the city. Starting with the horizontal ones I would try to estimate the number of roads going from east to west in each rectangle(depending on the type of area: residential, commercial or a highway) Similarly I would try to estimate the number of roads going from north to south in each vertical rectangle. Now I have the average number of roads per unit length and per unit breadth. Now, I can calculate the average number of roads intersecting per rectangle. Now if I have the data, I can also use the traffic density data to further improve my estimate, i.e. whether the traffic light is required in that rectangle or not.(depending upon the traffic density)
Q: Lets say that golden quadrilateral gets completed tomorrow. What would be its impact on the sales of Ashok Leyland?
Me: Sir, they would increase, as more and more traffic will shift from railways to roadways as the average time taken by road will decrease.
Q: If I say that the sales will decreases by road, the truk will make the same number of trips in less amount of time, thereby rendering overcapacity in the road transport market therefore the sales will decrease.
Me: (I actually didn't let him complete, I interrupted him in between and said that I got the logic)
Tips: Don't try to overstate the facts.
