Interview preparation journey
Preparation
Duration: 3 Months
Topics: Data Structures, Pointers, OOPS, System Design, Algorithms, Dynamic Programming
Tip 1 : You must have a grip over Data Structures and algorithms. Your concepts must be crystal clear. Pick one coding platform and try to practice at least 7-10 coding questions everyday. I completed around 200+ questions on Leetcode, 200+ questions on Geek For Geeks and around 30-40 questions on InterviewBit.
Tip 2 : After attempting any coding problem, analyze its time and space complexity. See, if you can further optimize your solution. You can always check the editorials and compare your solution with it.
Tip 3 : Apart from coding questions keep studying concepts of Operating Systems, databases and object oriented programming. You can always refer to Geeks For Geeks articles for it. Also, Coding Ninja's Data Structures and algorithms course in C++ helped me a lot in improving my OOPS concepts specifically.
Application process
Where: Campus
Eligibility: Above 7CGPA
Tip 1 : You do not need to have a long list of projects on your resume. One good project with proper knowledge of it will do good. Similarly, do not list down several number of skills. Few skills but roper knowledge of them are enough.
Tip 2 : Do not fake anything on your resume. The interviewer gets to know about it by asking questions. If you aren't able to answer, it leaves a negative impact.

Asked in companies
Ninja has a number ‘N’. He wants to print the pattern in such a way that the outer rectangle is of the number ‘N’ and the number goes on decreasing as we move inside the rectangles.
For example, if ‘N’ = 4, then pattern will be:
4 4 4 4 4 4 4
4 3 3 3 3 3 4
4 3 2 2 2 3 4
4 3 2 1 2 3 4
4 3 2 2 2 3 4
4 3 3 3 3 3 4
4 4 4 4 4 4 4
