Application story
My first-ever internship experience was through ClearExam, which I secured via on-campus placement. The opportunity was provided through the internship mela organized by Amity University. My greatest motivation and source of zest come from my mom, who constantly supports and admires me. I owe my gratitude to my faculty members and the six months of hard-earned practical and theoretical knowledge. The opportunity was facilitated by the Corporate Resource Center at Amity University, during the internship mela organized by the university itself. This was the first organization to hire software development interns. Interviews and the written coding/aptitude exam were held on the university forum.
Why selected/rejected for the role?
I was selected for the role since I cleared the assignment round successfully, answering all three coding questions with all test cases. Additionally, I excelled in meeting all the job requirements holistically, including certifications, prior projects, and subject scores.

The coding and aptitude round took place at the university and lasted for about 120 minutes. Each round was an elimination round. The first phase of questions was for aptitude. After clearing that, the coding screen would appear. The coding section comprised three levels: easy, medium, and hard. All were mandatory to qualify for the round, with test cases. Out of 10 questions, at least 5 should run. Only 10 questions were from aptitude and verbal reasoning. The rest of the questions were based on DPP and algorithms.

Codenation

You are given two integers 'n' and 'r' and a prime number 'p'. Your task is to find (nCr) % p where nCr can be calculated as n! / (r! * (n - r)!).

Note : 

N!  =  1 * 2 * 3 *... N

Sample Input  : 

5 2 11

4 3 13 

Sample Output : 

10 

Explanation for Sample Output :

 In test case 1, n = 5, r = 2, and p = 11

 n C r = 5 C 2 = (5 * 4) / (2!) = 10

 n C r % p = 10 % 11 = 10.

 So the answer will be 10.

All sorts of cultural and HR questions were asked in the round to better understand my personality and overall perspective, aiming to choose me for the opportunity.

1. Tell me something about yourself.

Problem approach

In response to this question, typically asked as an icebreaker in interviews, I provided a brief overview of my education, work experience, certifications, and skills. Additionally, I thanked the interviewer for the opportunity to introduce myself and be interviewed. I emphasized my soft skills, including being optimistic, smart, self-confident, hardworking, and having a positive mindset. Furthermore, I discussed my technical skills, which include proficiency in Java and C programming languages, HTML, as well as digital skills. I also mentioned my strong command of MS Excel and web technologies. Finally, I shared my interests and hobbies, such as dancing, Internet surfing, playing chess, listening to music, and reading news articles on my mobile phone.

My time management skills are exceptional, and I'm well-organized, efficient, and systematic. I find satisfaction in excelling at my job and consider it an honor and privilege to work for an established company like yours. I am goal-oriented and believe that my abilities align well with your requirements. Through this position, I aim to showcase my technical skills to contribute to the company's development and drive substantial financial growth through my work.


PRO TIP: Focus on your strengths related to the job you are applying for. For example, if you are applying for Data Analyst roles, you might mention strengths such as excellent business management and coding skills, problem-solving abilities, and the capacity to remain calm when dealing with large amounts of data.
