On March 6, 2022, I participated in HackwithInfy 2022. It’s a yearly contest that consists of 3 programming problems, after which you advance to further rounds and ultimately a Hackathon in the finals. I solved 1 problem completely (100% test cases) and another problem partially (only 10 % test cases). I received a Pre-Placement Interview Opportunity for the role of Digital Specialist Engineer at Infosys.

The Interview was scheduled for 12th May, the Duration was 40 minutes. Strangely the Interviewer didn’t introduce himself, nor did he ask for my introduction. He proceeded to ask me the following questions :

  • How are you?
  • How good are you at programming?
Given a string, find its first non-repeating character
  ANSWER: "E"

Find the largest word in the dictionary by deleting some characters of a given string

  • Differentiate between Delete and truncate.
  • Explain Joins.
  • Any networking protocols that you know?
  • Client – Server architecture.
  • Will there be any issue in switching to technologies that you don’t know, about for any project that we assign?
  • How long are you planning to work for Infosys, is it for a short duration?
  • Any plans for higher studies?
  • What if in a project you have to work alone with no help available, will you be able to do it and learn technologies according to that?
