Status: B.Tech
Position: SE at JPMC
YOE : 2 and 8 months
Location: Pune

Online Assessment : 28
Hackerrank test with 2 coding problems

First Round (DSA):
I have been asked two simple questions as following
1. Write a method to flatten a nested list. Similar to flatten in python numpy.
Inteviewer asked for both recursive and stack based solution
2. Given an array of integer and an element, k, find the index of the element where it will be located if array is sorted.
expected time complexity is less than O(n)
solution -> simply find out count of elements less than k. The answer will be count.

Second Round (LLD and Code review):

1. In this round firstly I was provided with a sample method and asked to review it. It was written in Java. So I have used knowledge of SOLID principles and design patterns to pin point some optimizations.

2. Later I was asked a simple LLD problem as follows.
   We have one UI with 3 buttons red, blue and green along with one more button as "calculate". User can click any of those 3 buttons any amount of times. When he clicks calculate we want to display count of green, blue and red. Interviewer wanted me to design api and database for this solution.
   I have explained him about db structure which db is more suitable and the api routes, method types. Also in the end I have explained how we can optimize our solution if we use cache service like redis.

Third Round (Hiring Manager):
In this round I have been asked about my recent project in detail along with some behavioural questions.
Later I was asked one simple dsa problem.

Overall Interviews were great, But the process was really exhausting. I have been reffer in last week of october, received test in last week of january, rounds were scheduled in last week of feb and start of march.
In between the process HR doesn't pick up your calls or explains anything in detail. Surely PayPal have to streamline the total process of interview and keep candiate posted about their application.

Hope this helps..
