Accolite Digital Interview Experience for Intern + FTE | On-Campus 2022

In our college campus recruitment process will have an online test (MCQs – 30 min/30Que & Coding Round – 60min duration), followed by technical (2 levels) and personal interview rounds, all Interview sessions conducted virtually. No. of rounds may vary from college to college.

Assessment 1: In this, we have to attempt a 30 min assessment at the Eduthrill platform, which consists of 30 questions. Questions are related to Data Structures and Algorithms, Operating systems, Object-Oriented Programming, Database Management systems, Networking, Quantitative Aptitude, and Reasoning.

Assessment 2(Coding Round): We have to solve 1 coding question in 1 hour in this round.

We are given the desired array target[ ] containing n elements. Compute and return the smallest possible number of the operations needed to change the array from all zeros to the desired array. They have changed the story of the question, else the concept is totally the same.

Technical Interview Round-1 (1hour+): After the coding round, I got the mail and call from HR on the same day, Informing me about the next round. I have gone through the previous Interview Experiences at GeeksforGeeks and Glassdoor. (But mostly your interview is based on your resume and skillsets)

The interviewer started with the introduction part and then he asked:

What are OOPs, Class, Objects, features of OOP, why do we need OOP?
Types of Polymorphism(Functional and Operator Overloading)
Encapsulation
Inheritance.
(Collections (only If you know C++ and Java, In my case I directly tell him “I’m leaner towards Python”)).
Then He asks me about Data Structures and Algorithms in python (List, Tuple, Dictionary, sorting algo – bubble, merge)
Then he asks me to share my VS Code screen and give me a problem: Given an array and a target value, check for pairs in the array with sum as target (NO REPETITION OF PAIRS).
After that, he moves to my projects and asks about that: covering (what is that project, Technology used, deep questions on that tech stuff)(almost 10-15 mins discussion)
After that we move to DBMS and OS:
OS – (Process and Threads)
DBMS – Joins(Inner, left-outer, right-outer), 2nd Highest Salary Query, Normalisation(all types)
In the end, he asked me whether I had any questions for him. I asked him about my feedback.

Technical Interview Round-2 (1hour+): I got the result of Technical Interview 1 within 2 hrs, that I have cleared that round and they schedule the next technical round after 3 hrs.

The interviewer asked me to introduce myself, my projects, my past internship, and my co-curricular activities. (He asks too many tech questions about my experience). Ask about CN Fundamentals (HTTP, HTTPS, SSL certificate).
DBMS – Joins(Inner, left-outer, right-outer), Normalisation(all types), this time he asks me to write a query for left join on Given example.
My Project is in the Domain of AI/ML/Web-dev. So he asks me about supervised learning algorithms -> Linear regression, Logistic regression, Decision tree, Random Forest -> How to calculate the accuracy of model (Ans: for Linear reg : RMS Value and for logistic reg : Confusion Matrix ) -> What is Confusion Matrix -> 4 Quadrants of Confusion Matrix (TP,TN,P,N)-> formula to calculate accuracy from confusion matrix (accuracy = (TP+TN)/(P+N)), Information Gain + Formula and Entropy.(Going deeper by extracting keywords from your previous answers)
Then he moved to Data Preprocessing, Methods of Data Cleaning. (Basics, I explain all things w.r.t my projects)
In the end, he asked me whether I had any questions for him. I asked him about my feedback.

HR Interview Round-3(45-60 mins): After two technical interviews, I got the result the same day, that I have cleared it and they will schedule an HR interview tomorrow.

The interviewer asked (ALL TOP HR QUESTIONS):
