There were 50 MCQ questions including aptitude, technical portions. Aptitude part was more dominant with approximately 35 questions & almost 15 technical questions. These questions covered following topics :- 

– Quantitative aptitude (relative speed, distance topic had 4-5 questions & rest 1-2 question from each topic). Questions were not very difficult but were tricky . 

– English – Questions containing Paragraph of 4-5 lines. We have to select the best suited summary / heading/ meaning/ conveyed message for above . Atmost 4 questions were from this category.

Aptitude questions were logical & complex calculations were not required. 

Round 2-(Technical Interview) 

1) Given a string, reverse it.. Firstly, i told an O(n) approach then reduced it to O(n/2). This was just ice breaking question very easy. 

2) List all Permutation of a String. Approach & code. 

3) You are given huge amount of integer data & a continuous stream of data is coming. How will you find kth largest element always. 

At first i started with quick select , then was asked to think better. Then, my next approach was taking an amount of data like 10MB always & using Merge Sort to sort the large amount of data. But then i realized it could be made better by using priority queue of size k. So, i gave them this approach of taking k size priority queue & every time an element greater than the smallest element in the queue comes we replace it by new element. They were satisfied with this approach. 

4)Projects – 
Many questions were asked on my projects. Few situations were given & I was supposed to do some modification on one of my project database to handle these situations. 
Other project related technical questions were asked .

Note: Not all rows can be made to 6 , you must be able to tell this 1 1 1 can’t be done..
