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.

Experience: First 4 rounds on day 1 and this are just to shortlist for more rounds on some other day.
Tips: They will focus on almost all the concepts of computer science.You need to practice a lot and start it right now. Should be easy if you have prepared well enough. Use your holidays to start preparing for placements.

General Tips: Sooner you start, better your placement will be as lack of practice & last day study works only for exams but never for interviews. You'll get enough time to prepare for interviews once you get shortlisted. Focus on it even if you are placed already.

Interview Preparation Tips

Round: Technical Interview
Experience: On-site interview (5 hours).

4 back-to-back 45-minute coding interviews, followed by a design interview, with a lunch break with a Googler in the middle.

The first coding interview was a set of (surprisingly) trivial (no algorithms needed) incremental coding questions.

The two next coding interviews were problems straight from the "Cracking the coding interview" book. Even though I divulged that I'd solved pretty much exactly the same problem before, they didn't give me an alternative problem and I quickly coded up a general and optimal solution for the problems. Follow-up in-depth questions were minimal and not hard.

The last coding question was a pure algorithm question related to search trees/tries. No coding required, spent the whole time reasoning about the most effective algorithm. This was a bit of a brain twister.

The design question was related to high-level system design (not OO design) for storage and search in geographic data. Focus was effective search as well as scalability both in traffic and data volumes.

Tips: Read "Cracking the coding interview" or other similar literature. Solve all the problems and you should be good to go. If you solve a bunch of problems at HackerRank (or similar) as well, you'll have the added bonus of training on how to generalize the algorithms.

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.
