What will you learn in the Interview Preparation Course in Coding Ninjas?

The course focuses on four topics, and they are:

Time and Space Complexity (9 hours lecture):


Order complexity analysis, Theoretical complexity analysis, Time complexity analysis of searching and recursive algorithms, Theoretical space complexity, Space complexity analysis of merge sort

Arrays (7.5 hours lecture ):


  • Introduction to arrays: Introduction to arrays, How arrays are stored in memory, Passing arrays to functions
  • Searching and sorting: Understanding Binary Search, Selection sort, Bubble sort, Insertion sort, Merging two sorted arrays

Strings and 2D Array (7 hours lecture):


  • Strings: Introduction to strings, storage of strings and their inbuilt functions
  • 2D Arrays: 2D arrays, Storage of 2D arrays, Example problems using 2D Arrays

Advanced-Data Structures (8 hours lecture):


  • Hashmaps: Introduction to Hashmaps, Inbuilt Hashmap, Hash functions, Collision handling, Insert and Delete operation implementation in hashmap, Load factor, Rehashing.

Apart from the lectures given above, you will also have MCQs, tests, and coding problems. A total of 50 MCQs will be covered in the duration of the course. MCQ questions will help working professionals to revise their past knowledge.

There will be one test at the end of the course that would improve your skills and help you understand your progress. This test also helps you to recognise and concentrate on the key topics. There will be a total of 22 Coding Problems to test how efficient you are indifferent concepts.

These problems will be given as a part of lectures immediately after the completion of each concept to ensure that you recognise your level of understanding of the concepts. Coding Problems would also help you to think about the applications of each concept and would enhance your understanding and skills. 

Coding Problems will be given in these topics:


Four coding problems will be given based on Array.

The problems will cover topics such as Array Sum, Linear Search, Arrange numbers in an array, swap alternate.

String and 2D Array:

8 coding problems will be given based on String and 2D Array.

The problems will cover topics such as Count words, check palindrome, print all substrings, reverse string word wise, row-wise sum, largest row or column, wave print, spiral print.


10 coding problems will be given based on hashmap.

The problems will cover topics such as Maximum frequency number, print intersection, pair sum to 0, longest consecutive sequence, pairs with difference K, zero sum sub-array, vertical order, make strings anagram, longest subset, nearest repetition.

Practising coding problems is very beneficial for freshers since they do not have much experience and this would enhance their application-level skills. MCQs and Coding Problems will give professionals and insight into what are the most important topics for an interview and hence would prevent them from spending time revising topics that are not very important.
