• It contains 2 sections, 10 Aptitude questions, and 10 C- code Snippets
• It is a paper-based test you will be provided with question paper, a Rough sheet, and a sheet to write your answers with your basic info

• Aptitude: (Not mcq's) Easy level:

• Tips: Be calm, you can solve most of the questions
• Don't get tensed and Don't write wrong answers in solution sheet, bcoz even you got right answer, there will be no use if you don't right correctly

• C-code snippets Easy Level(But tricky): It contains pointers, static, global, and local variables, strings, and recursion-related code snippets provided and we need to write the expected output.

Round - 2: Coding-1

• Total 6 questions
• we need to execute code in our local IDE and need to explain to the recruitment team that came to our clg.
• They will note everything like time of submission and they will check for edge cases and write comments related to that question how we explained or something
• Coding questions :
  1. Print a given matrix in spiral form: https://www.geeksforgeeks.org/dsa/print-a-given-matrix-in-spiral-form/
  2. Infix string expression evaluation : https://www.geeksforgeeks.org/dsa/expression-evaluation/
