Ninjacart Software Developer Intern Interview Questions and Answers

Tip 1 : Practice Atleast 300 Questions on leetcode (150 easy, 100 medium and 50 hard )
Tip 2 : Make atleast one big project which includes (DB, backend and frontend). Because in Hiring Manager round we have to discuss our resume for about 45mins to 1 Hr so having 1 or 2 big projects on the resume is always good to have otherwise HM will go towards core subjects Like OOP/OS/Networks which are often tricky.
Tip 3 : Think out of the box while solving a Question think of all the variants in which this questions can be asked. Let's take an example of simple question like two sum here we have to find a pair in an array whose sum is equal to given value. Now what if Interviewer asked to find three numbers instead of 2 or maybe find k numbers whose sum is equal to a given number. So it is always good to think out of the box and generalise the solution.
Tip 4 : Always try to solve each question in different ways. You should know both the bruteforce solution and the optimal one.
Tip 5 : When you solve a Question try to learn as much possible from a single Question for eg if you try to solve a Tree question then it is good to know both the iterative and recursive solution as sometimes Interviewer may introduce some constraints that due to huge test case recursive solution is not possible.
Tip 6 : 3-4 days before the interview start preparing using interviewbit as it contains all the important questions topic wise. I usually solve Interviewbit before the interview. No doubt Leetcode is good in terms of UI, Test cases and Easy to use but Interviewbit is more organised. I myself have done all the Interviewbit Questions multiple times.

Tip 1 : Always attached your Project links in your resume. As it seems your project is genuine and you are confident in showing your projects
Tip 2 : Don't add unnecessary things in your resume which are not related to the job, like your 10th class winning tournament certificate or managing a college society. These things didn't create any impact on your profile and takes an unnecessary space in your resume.
Tip 3 : Always make a 1-page resume. If you are making more than 1 page then it means you have added a lot of unnecessary information which are not related to the job profile.
Tip 4 : Always show your Project and Past experience on top, just after your basic info and education. Since these are the things which should be on top to showcast the skills.
