It had 4 sections.

  • Technical MCQs: It had 20 technical MCQs which consisted of questions based on fundamentals of Data Structures and Algorithm, DBMS, SQL, Networking, and Computer Fundamentals.
  • Coding Section: The time allotted was 1 hour to complete 2 coding questions
  • Given Q queries each with inputs L and R. Find all the composite numbers within the range of [L, L+1,……., R-1, R], where L and R are inclusive. (Hint-Use Sieve of Eratosthenes to find the prime and store it in an array and then find all the composite numbers in that range).
  • Algorithm Section: In this section, you had to write an algorithm for 2 programs in 15 minutes, We had to write an algorithm to find the maximum sum submatrix which could be solved using Kadane’s algorithm, the second question was based on a greedy approach, (Note in the Algorithm section, we were told to write just the pseudo-code in a blank space given)


  • Try to pass 70% of the total test case in the coding section and at least one question in the algorithm round.

Round 2: Virtual Technical Interview

  • Almost 50 students were shortlisted for the Technical Interview round including me.
  • In the beginning, the interviewer asked me if I had any questions for him about the hiring process then he asked me to introduce myself.
  • He asked questions about my resume, starting with questions about my project which was based on  Web Development
  • He asked about the difference between JavaScript and typescript and also a difference between multithreading and multiprocessing(as I had mentioned multithreading in one of my projects).
  • There were no questions asked from the DSA part from me, but it depends on the interviewer and for me, he was aligned more towards my project side 
  • The results were announced in the next 1 hour and I was called for further rounds. Around 25 students were selected for further rounds.


  • Be thorough with the Job description of the company, as for Fidelity it needed a good front-end web developer and someone should be well known with either ReactJS or AngularJS(Which I was not good with).
  • You should be thorough with each and every part of your resume that you have mentioned, be realistic with your resume and dont write things that you don’t know(Specially related to Projects).
  • Your answer to questions should be such that you mention the things you know in your answer because the follow-up questions are based on your answer.
  • Try to answer something related to the topic asked and dont be blank.

Round 3: Virtual HR Interview

  • In the HR round, these were the following questions were asked
  • Introduce yourself?
  • What does fidelity investment do?
  • What are your strengths and weaknesses?
  • Where do you see yourself in the next 5 years?
  • In my Resume I mentioned I was an active member of a rotary club , so they asked questions like what was your role in the club, have you handled any pressure situation in the club, if yes please expain.

This interview was short around 15-20 minutes and finally, they selected 15 students for the Summer Internship(I was not selected).
