JP Morgan Chase & Co. organized its first round for full-time analyst hiring on 27th February 2021. HackerRank was used as the platform for conducting the coding round. The round had 2 questions with a time limit of 75 minutes. The difficulty was fairly easy for anyone that has a little bit of coding practice in the past.
Each question was 50 marks for each with a total score of 100.
Online Test(Coding Round):
- Suppose we have a string s, we have to find the count of contiguous substrings that have the same number of 0’s and 1’s, and all the 0’s and all the 1’s in these substrings are grouped consecutively. If substrings occur multiple times are counted the number of times they occur. (https://www.geeksforgeeks.org/given-binary-string-count-number-substrings-start-end-1/)
- Merge Intervals: Given an array of intervals where intervals[i] = [starti, endi], merge all overlapping intervals and return an array of the non-overlapping intervals that cover all the intervals in the input. (https://www.geeksforgeeks.org/merging-intervals/)
I was able to complete both the questions at a really high speed due to my recent practice. Sorting algorithms and vector manipulation helped in the second question a lot. I Will update you when I have information about the rounds that follow.
