Oneshield Interview Experience (On-Campus)

One shield visited our Campus for Placements. There were 4 rounds in total:

• Online test
• Coding Round
• Technical Round 
• Final Round

Online Test: Online tests consisted of aptitude tests where there was logical reasoning, quantitative aptitude, etc. It was 50 questions in 15 minutes then there was a personality test of 10-12 minutes and an emoticon test of 15 minutes. The emoticon test had questions where we were put in different situations and we had to match the facial reaction as how one person would react.

Coding Round: I cleared the online test and there was a Pen and Paper Coding Round this was a 1 hr Round where 3 coding questions were given 

• 1st was to rearrange the numbers in the array such that the positive elements are in descending order and the negative elements are in ascending order afterward 
• https://www.geeksforgeeks.org/delete-all-odd-nodes-of-a-circular-linked-list/
• https://www.geeksforgeeks.org/minimum-time-required-so-that-all-oranges-become-rotten/

Solved all the coding questions and moved to the next round

Technical Round 1: The interview started with telling me about myself followed by asking how were the coding questions the interviewer glanced through my resume and started asking basic questions from oops and dsa  such as

• what is function overloading
• what is a binary search
• Give an example of the circular queue

Then the interviewer asked if I know probability I said yes so she asked one question on probability which was given a bag of balls containing blue balls and red balls what is the probability of when removing 2 balls we find exactly one red ball. I couldn’t answer it I said idk

then since I made a project using DBMS and MySQL she told me to draw the relational model of my project database followed by a SQL query on it. I drew the relational model and answered the SQL query correctly

Result: moved to the final round

Final Round: This round also started with telling me about yourself then I was asked to explain my codes from the online coding test followed by a few questions from oops and dsa like:

• what are static members
• can we write code in a destructor 
• why are linked list preferred over arrays 
• what are vectors and dictionaries
• then it ended with draw the database of your project

Result : Accepted
