Amadeus Member Technical Staff Interview Questions, Process, and Tips

Round: Test
Tips: You should be familiar with OOP concepts and a few concepts like binary tree. Also aptitude and quant questions (like in CAT). They will test your coding skills thoroughly during the test (only in the prog. language that you opted) and will question your logic and your approach to the problem. Be thorough with your coding basics.

Round: Technical Interview
Tips: The tech rounds focused mostly on coding. You can choose any programming language that you are comfortable with. They are not insistent that you know Java. I chose C++. The interviewers mainly look at how you approach the questions (the way you solve the question - if its the most efficient/fastest solution to the problem). They will also ask quite a lot of puzzles (the ones you can prepare from Heard on the street, 400 puzzles etc.) and a few CAT quant qns.

Round: HR Interview
Experience: HR round is very easy
Tips: basic qns that you will prepare for any company. Be sure to attend the PPT; the HR will surely ask you a few qns from it. Also know a bit about the company and the profile you are sitting for.

General Tips: The test is the only criteria for getting shortlisted to the interview round. There are certain Oracle profiles that are only open for CS and one which has a CG cutoff of 8.5. But for the App Dev profile there was no CG cutoff. your performance in the test is most important,because they generally do not entertain walkins during interview. Resume is not that important. Only HR team will have a look at it. If you have any coding experience (from any projects) or Java certification then its an added bonus. But its not mandatory.
1st year- concentrate on CGPA
2nd year - find out what you want(core or noncore). Do internships in starts ups or finance or consult companies if aiming for non-core. PORs are important
3rd year- internships.
4th year- start placement preparation very early. 
Work well on your project if you want to go for core.
College Name: IIT MADRAS

Round: Resume Shortlist
Experience: CGPA cutoff for qualifying the online test was 7. And all branches were eligible to take the test.

College Name: BITS Pilani - Hyderabad

Round: Resume Shortlist
Experience: They came to recruit on campus in NIT Trichy. They had come for 4 profiles - Application Development, Server Technologies, MySQL and SUN microsystems
Tips: It's mostly about CGPA and your profile. Most of the people about CGPA of 7.00 we're shortlisted

Round: Problem Statement
Experience: 1) Reversing a linked list
2) K closest stars
3) Find the range of indices of occurrence of a duplicated number in a sorted array.
Tips: Easy questions. Do geeksforgeeks and leetcode and should be a breeze.

Round: Technical Interview
Experience: Explained in details about my projects and the reasoning behind the approaches followed.
Tips: Try to thoroughly know about your projects and the different approaches you took and then this round should be easy.

The interviewer does a lot of cross questioning so you should really know the project inside out.

Round: Technical Interview
Experience: Details discussion about the approach and the different ways of optimizing the space and time complexities.
Tips: It's a discussion where they are trying to gauge your ability to think through a problem and be able to discuss the complexities and why did you prefer your solution.

Round: Technical Interview
Experience: A median is the n/2th number in case n is odd or the average of (n/2 and (n+1)/2 ) numbers when n is even. So,for the first question I used two heaps. One minheap and one maxheap. The minheap is used to store the larger set of numbers and the max heap is used to store the smaller set of numbers. We try to maintain an even sized heaps. And then try to get the top of the max heap if n is odd, otherwise the average of the minheap and maxheap in case n is even. Had to code in C++.

Fisher-yates shuffle algorithm. Had to code in C++.
Tips: Standard Geeksforgeeks questions.

Skills: C++, MARKETING APTITUDE, SQL, Algorithmic Approach To Problem Solving, Data Structures
