Finding smallest of 4 numbers without using >.< and min function in Java.
Initialize a variable with the first number
Compare it with the remaining numbers using if-else statements
If a smaller number is found, update the variable
Repeat until all numbers are compared
The final value of the variable will be the smallest number

Interview Questionnaire
4 Questions
- Q1. Tell me about your internship, B.Tech project(BTP), CV
- Q2. Implement LRU cache.
- Ans.
Implement LRU cache
LRU stands for Least Recently Used
It is a cache eviction policy that removes the least recently used item
It can be implemented using a doubly linked list and a hash map
Newly accessed items are moved to the front of the list
When the cache is full, the item at the end of the list is removed
- Q3. What is virtual memory? Will we need virtual memory even if we have infinite amount of RAM?
- Ans.
Virtual memory is a memory management technique that allows a computer to use more memory than it physically has.
Virtual memory uses a combination of RAM and hard disk space to store data.
It allows programs to use more memory than is physically available.
If a program tries to access memory that is not currently in RAM, it will be swapped in from the hard disk.
Even if we had infinite RAM, virtual memory would still be n...
- Q4. Given an array, Find out maximum length of subarray where max of subarray <= 2*min of subarray
- Ans.
Find maximum length of subarray where max <= 2*min.
Iterate through array and keep track of max and min values.
Update max length when condition is met.
Time complexity: O(n)
Interview Preparation Tips
Experience: No CPI cut off and It was open for all departments.
Round: Test
Experience: In muliple choice question Mostly questions were base on maths, probability, c programs, algorithms, Systems. If you are prepared then Questions were not that much tough. Keep strong concepts of Operating systems. For subjective part, Some problems were from maths proofs, some were from probability, some were from algo. We had to write algorithms. etc
Duration: 180 minutes
Round: Problem Statement
Experience: Questions were doable.
Round: Interview
Experience: Everyone was cool, They made me feel comfortable and then started asking questions.
Tips: If you have good rank in online coding competition, do mention it in CV.Most of the students think that GS asks only probability-puzzles. They did not asked me any question on probability or puzzle. Everything they asked was based on Algorithms problems and Operating system. I think it depends on team for which they are hiring. Most important point is don’t lose hope because you have low CPI or you are not good at something. Keep Operating systems fundamental concepts strong.
General Tips: We should balance in Placement and Compititive online coding. Keep in mind Placements and Compititive online coding are some what different things. Keep on improving our mistakes on daily basis. I would strongly suggest you to do introspection daily it will help you to find out your weaknesses and strong points, where we are going wrong etc. There are two thing on which we shoud focus.1. Preparation (I have told everything requered for preparation).2. Get output of all hard work. How to keep our mind on 100% output while the actual exam(placement).For this, I used to go for physical exercise daily in the morning and medidate for 20-30 minutes. Along with exercise i used to do Sudarshan Kriya(Art of Living). Meditation has lot of power :).
Skill Tips: Keep your OS fundamentals strong. To improve codgin skills practice as many problems as you can. Regularly participate in online coding competitions it really helps to solve or approach any new problem. Many time instead of correct answer the approach to solve the problems is very important. How you think, How you approach the problem is checked in interview.
Skills: Coding Skills, Operating Systems , Problem solving skills

Timing: 12PM
Due to covid, the interviews happened over a video call on Zoom. They also shared an IDE link where we could write our code and the interview could see it.
The interviewer was very polite and helpful. She dropped hints in between to help me reach the final solution when I was stuck or needed some clarity. She wanted to check how analytically I could solve the problem. She focused more on my approaches towards the problem.
There was also a brief discussion on my resume and projects.

Interview Preparation Tips
Tip 1 : Focus on Data Structures and Algorithms. Practising questions based on them every day is the key to succeeding. You can enroll into a Data Structures and Algorithms course by Coding Ninjas. This course helped me build a strong foundation in these topics. I also recommend platforms like LeetCode and InterviewBit for further practice.
Tip 2 : During your interview THINK OUT LOUD!!! It is very important that you voice your approach towards the problem otherwise interviewer will have no clue what you are thinking.
Tip 3 : Do give mock interviews to some college senior or mentor. They help you understand how to express your thought process better (Think out loud) and also reduce the interview stress and anxiety.
Tip 1 : In order to make a strong resume you must include at least 2-3 Projects and an intern/work experience. Mention all your skills which you are confident of in your resume.
Tip 2 : Try to make it of one page only. You can use overleaf to make your resume.
