# Factset Interview Experience |Set2 (On-Campus)

I find GeeksforGeeks very helpful! It helped me prepare for my FactSet interview. Hereâ€™s my interview experience for FactSet which came to my college for recruitment. Round 1 (Written Coding) : 3 coding questions. (Pen and Paper mode Examination) -print the element that is common in all rows of a matrix
```
Eg: 2 3 7

1 7 8              ans is 7.

6 9 7 ```
Find median of two sorted arrays. O(logM + logN) –Zig-zag traversal of binary tree. Round 2(technical interview): 2 interviewers were there and the interview went on for about 60 minutes. Questions they asked were mainly programming and puzzles and some of the operating system and database concepts. -Given an array and a number k, find all pairs of numbers in array whose sum is least near to k. –How to find intersecting point of two linked lists. (most efficient way). -Design Database schema for supermarket (Reliance Fresh) taking care of all the factors about details of discounts and offers to customers. -puzzle as follows: __ __ __ __ __ __ __ __ __ __ 0 1 2 3 4 5 6 7 8 9 Fill numbers in the above blank from 0-9 such that number X coming over any number Y means Y should be in X blanks. For eg: if 2 comes over 0 means 0 should be present in 2 blanks. Round 3 (technical interview + HR): 2 interviewers and 60 minute duration. It was mixture of both technical and HR round. -Tell me about youself? –Given a matrix of characters and a string, find the first index of string in matrix. String can be horizontally,vertically, diagonally present in any direction.
