Round 1(Online Test – 100 mins): It was divided into 3 sections
- Verbal: 12 Questions 15 mins
- Business Aptitude: 15 Questions 25 mins
- Coding: 2 questions 60 mins
Coding questions asked were:
1. Given N delivery persons (with IDs from 0 to N-1). When a delivery is scheduled, the distance of the destinations from the office is informed to the delivery person. If the delivery location is updated, the delivery person is informed of the extra distance in a message separate from the message that informed him of the original distance. If the new location is outside the delivery region of the branch then the delivery person receives extra compensation to deliver the product which is given only once to a delivery person. The company system generates two types of instructions.
- The system informs the delivery person of the extra distance for an updated location.
- Calculates the total salary of a group of delivery persons having IDs in the given range.
- Question related to Graph.
Round 2(Technical Interview – 60 mins): The interview started with a brief introduction about myself.
- Moving further he asked me why I choose to enter the software industry being an electrical engineer followed by the difference between motor, Generator, and Transformer and also the direction of rotation of motor and generator.
- Next, he asked me about which languages I’m comfortable with and where did I use them. He asked me to state the difference between pandas and NumPy.
- I had published a research paper so he asked me to explain the entire paper in a way that laymen can understand.

Tips:
- They do consider the level of difficulty if you are not from a Computer Science background.
- All they focus on is how much effort you put in and your ability to grasp new concepts.
- So even if you know fewer concepts, have a clear understanding of them.
- Be confident and shine.
