Round-II(Technical Interview-I)

  • Some questions from my resume were asked, and some about prior intern experiences.

  • Some questions on OOPS followed this; the concepts were checked in-depth and not superficially. (OOPS sheat by Swapnil Sir is a good source for revision).

  • Then they asked me this puzzle. This is a good source of preparation.

  • Post theoretical questions, they asked me two programming questions. Both were Leetcode Medium level questions based on graphs and trees
  • Decent Problem Solving Practise and in-depth knowledge about OOPS is required to clear this round

    • The first question was to design a spell checker (Hash Table and Trie Solution were not expected. A randomized data structure was to be designed)
    • The next question was to design a class-like feature of C++ in the C language

This was followed by a discussion on language-specific features of C/C++ and questions on compiler design, computer architecture, OOPS, and some data structures questions based on a project in my resume.
