LTI conducts a coding challenge every year in order to incorporate skilled future tech leaders. The company believes that the students who perform exceptionally well in the challenge can solve real-world business problems using Cloud, Digital Technology, and Data Analytics. The LTI Infinity Coding Challenge 2021 is a 2-hour coding competition that is held virtually. There are three levels in this coding challenge that would determine the annual packages students are offered.

Recommended Topic, Cognizant Eligibility Criteria

Exam Pattern, Selection Process, and Salary

The challenge has three levels, with each level unlocking once candidates are able to solve the questions in the previous level. The first level of code evaluation will be conducted by an automated system after which the subsequent levels will be evaluated by the leadership at Larsen and Toubro Infotech. 

Each level makes candidates eligible for packages of 6.5, 8 and 10 LPA INR, respectively.

Eligibility Criteria

One can apply for the LTI Infinity Coding Challenge provided he/she meets the eligibility criteria mentioned below:

  • The candidate must graduate in the year 2021.
  • B.Tech and B.E are acceptable qualifications.
  • Computer Science, Information Technology, all circuit branches and all branches that have hands-on programming are accepted.
  • The candidate isn’t allowed to have a gap year in the middle of any course.
  • The candidate must have at least 60% or equivalent CGPA throughout his/her academic career.
  • The candidate must not have more than two active backlogs at the time of the interview process.
  • The candidate must have no backlogs or re-attempts in the last semester of graduation.
  • The candidate must have no backlogs pending after the candidate’s final results are declared.
  • It is necessary for each candidate to have cleared both his/her Secondary School Certificate (SSC) and Higher Secondary Certificate (HSC) in the first attempt.
  • The course for graduation must be a full-time course, anything else is not acceptable.
  • The candidate must be a resident of India.
  • The institute from which the candidate graduates must be UGC or AICTE approved.

The LTI infinity coding challenge 2021 registration process is available on the LTI Official Website itself.

Syllabus for the LTI Infinity Coding Challenge 2021

LTI Infinity coding challenge 2021 syllabus is only based on Data Structures and Algorithms, OOPS concepts. One has to be well-versed with dynamic programming in order to solve the level 1, 2, 3 questions. 

The qualifying candidates must have knowledge in the topics mentioned below to be able to clear the LTI Infinity coding challenge 2021 interview questions:

  • PseudoCode
  • Programming Fundamentals
  • Database Management Systems
  • SQL
  • Networking
  • Object-Oriented Programming Systems
  • Networking
  • HTML
  • Software Development Life Cycle (SDLC)
  • Operating Systems

Previous Year Questions

When we look at the LTI infinity coding challenge 2020 questions, we can assume that the LTI Infinity coding challenge questions for 2021 will have a similar pattern as that of the LTI Infinity coding challenge previous year questions.

Here is one example problem along with its solution:

Question: Joe and Bottles

Joe has a crate with X bottles of different shapes arranged in a row. He traverses through the row and picks up bottles. He aims to pick the first Y bottles in the row.

Evaluate the number of differently shaped bottles that Joe would pick if he traverses through the Y bottles.

Input Specification

input1: X, number of bottles in the crate

input2: Y, number of bottles Joe sees in one traversal 

inputs: An array containing the bottle index Z to represent each bottle by unique tags/numbers (1<=Z<=1000). 

Bottles having the same shape are said to have the same index

Output Specification

The function should return the number of differently shaped bottles that Joe picks.


import java.util.HashSet;
import java.util.Scanner;
class JoeBottles{
public static void main(String args[])
	Scanner sc = new Scanner(System.in);
	int x = sc.nextInt();
	int y = sc.nextInt();
	int arr[] = new int[x];
	String b[] = sc.nextLine().split(" ");
	HashSet hsh = new HashSet<>();
	for(int j =0 ; i<b.length ;j++)
		arr[j] = Integer.parseInt(a[j]);

Interview Questions

If one qualifies for the coding challenge, then he or she needs to prepare for the interview process in order to face the LTI Infinity coding challenge 2021 interview questions. The interview will have a technical round and an HR round:

Technical Round: The interviewer will check the candidate’s strength in coding skills (C/C++/Java/Python), the candidate is also likely to face questions on OOPS concepts (Inheritance, Polymorphism, Data Abstraction etc.) and SDLC (Software Development Life Cycle). In addition to the questions from these areas, the interviewer might also enquire about the candidate’s projects and might also question on the topics mentioned in the ‘Syllabus’ section of this article.

HR Round: After the candidate qualifies for the Technical Round, he or she shall move onto the HR Round where the candidates are asked questions that determine their behavior. It might start off with a “Tell me about yourself” and then the HR digs in deeper to psychoanalyze the candidate. This is the final round of interviews that the candidate will face before he/she is selected for the job role.
