    Quick sort is a sorting algorithm that uses a divide-and-conquer approach to sort an array of elements.

    • It selects a pivot element and partitions the array into two sub-arrays, one with elements smaller than the pivot and the other with elements greater than the pivot.

    • The process is repeated recursively on the sub-arrays until the entire array is sorted.

    • It has an average time complexity of O(n log n) and is widely used

Interview Preparation Tips

Round: Test
Experience: I appeared for Amdocs through Campus Recruitment Process. Section 1,2,3 was not tough, if you have practiced RD Sharma then don't worry about these sections as it was the easiest part of the written test. After that there were two coding questions in which you can choose any language(C/C++/Java) to write your code. The code were easy, I mean it wasn't like Codechef problems. If you have ever made the programming assignments by yourself then you would definitely be able to crack this section. Even if you didn't make it then you can practice coding questions like finding H.C.F, L.C.M, Removing redundant number from array, finding whether the string is palindrome or not, finding whether the number is Armstrong number or not,etc,. Now comes the technical section that was little bit tough for those who haven't studied about UNIX ever. It was consisting of C, DBMS and Unix. C questions can easily be attempt by completing "Test your C Skills by Yashwant Kanedtkar", In DBMS most of the questions were query based, some PL/SQL questions were also there, in Unix most of the questions were from VI editor commands and some linux commands like sed, uniq, fdisk and very few questions were from shell scripting like, what will be the output of echo*. Overall the test was easy, since it is easy for everyone so you need to do lots of practice because out of more than 200 students only 39 cleared the written test in our campus.

Interview Preparation Tips

Round: Resume Shortlist
Experience: I had a standard resume for this company as per the norms of our institute’s placement cell. For Oracle I laid emphasis on my programming skills and projects related to it.

Round: Test
Experience: The first round was the written test that comprised of 5 sections – vocabulary, aptitude, pattern matching, logical reasoning and programming. The questions in the programming section were asked from data structures and C++. The questions in the programming section were mainly from trees (from data structures). Around 400 students appeared for their written test out of which around 100 were shortlisted.

Round: HR Interview
Experience: The next round was the interview round. They gave me some puzzles to solve and a program to write. One of the puzzles that I remember was that if I were to be given an egg then how would I determine its durability, i.e. how would I determine that from which floor do I need to throw the egg from so that the egg does not break if thrown from any floor below it.
For the coding question I was given a mathematical formula and I was asked to devise a code such that the program uses the formula and gives the output.
Tips: Prepare for Data Structures as well as the commonly asked puzzles for Oracle.

College Name: IIT ROORKEE
Motivation: Oracle is a reputed company in the space of software and ITeS. It had come to our campus with five profiles. The best means to know about all of them is to attend the pre-placement talk of the company.

I applied via Campus Placement and was interviewed in Dec 2016. There was 1 interview round.
