Nielsen Interview Experience for Internship + FTE | On-Campus 2021

  • Last Updated : 29 Jul, 2021

Nielsen visited our college in July 2021 offering internship + FTE. The hiring process had one Coding Round, two Interview Rounds.

Round 1(Coding Round): Coding Round had 3 questions.

  1. First one was simple, based on strings.
  2. The second was from arrays, we had to turn an array into a distinct array using a minimum number of operations by incrementing or decrementing an element,basically Codeforces Div2 B/C level.
  3. This one was a sequence similar to Fibonacci and we had to print the nth sequence of the element, a pattern could be seen by printing around 20-30 elements.

Solving 2 fully would help you proceed to the next round, around 30 students were shortlisted for further rounds.

Round 2(Technical Interview): This round began with usual, “introduce  yourself” and was divided into three parts.

  1. Questions from DBMS/OS/CN, I was asked how the Internet works, what is DNS, how would you optimize a problem, what is having higher priority space complexity or time complexity, SDLC, what projects you have done, etc.
  2. Live Coding: In these 2 questions were asked and we had to code on a screen share, quite simple compared to the coding test. I was asked to a) Reverse a string using Recursion and b) Implement any sorting algorithm: I wrote the code for MergeSort and was asked to optimise it.
  3. Puzzles, quickly glancing over GeeksForGeeks puzzles will definitely help you solve these. I was asked two puzzles, Using a 7-minute sand clock and a 4-minute sand clock, how would you measure 9 minutes, I couldn’t solve this and she gave hints, Second was how to divide a cake into 8 pieces using 3 Cuts, this was easy.

Round 2(Managerial +HR): This round consisted of behavioural questions like,



  • Have you worked in a team before?
  • How would you handle conflicts in team?
  • What projects have you done?
  • What complexities you faced in projects?
  • How is your final year project coming along and questions along these lines.

The next day results were declared and 4 including me were shortlisted.

My Tips:

  1. For Coding Round practice a lot of problems on Arrays and Strings from GeeksForGeeks.
  2. Know everything in your resume.
  3. Read last-minute notes of DBMS,OS,CN etc from GeeksForGeeks.
  4. Glance over the puzzles section.
  5. Be confident and honest in Managerial round.

Thank you and all the best 🙂
