First 10 minutes were just questions about resume and previous work experiences. Next 15 minutes were spent on the coding question and the last 5 minutes were left for the questions to the interviewer.
Coding question:
Given two integer arrays, find the first starting point of one array in the second array. Basically, second array is a subarray in the first array and you have to return the index of the starting point of the subarray. If subarray doesn't exist, then return -1.
Example:
Input:
[1,2,4,5,7,8]
[4,5]
Output: 2

Input:
[1,2,2,2,2,2,2,3]
[2,2,2,3]
Output: 4

I was able to do it in O(n* m) time complexity but please feel free to share if you have a better solution.
