Citrix Interview Questions, Process, and Tips

Round: Technical Interview
Experience: 1. On protocol
2. On my project in networking elective
3. On tcp/ip
Tips: story building helps generally. Make the guy feel comfortable and also showcase you are comfortable and chatty.

Round: Puzzle Interview
Experience: 1. Generic ones really copied from internet - he had a notebook from which he was reading out.
2. Something on balls, believe 8 of them... symmetry can't quite recollect (5 years back!)

Round: HR Interview
Experience: - smooth. They asked about writing myself in 2 min and he stares at you. He then asked questions on that. Make sure you bring out what company will benefit by hiring you and only you not next guy sitting. (I recollect telling him I may not know all but can definitely go out there and find what is really that all and get it done)

General Tips: Works if you don't care. It's tough actually do that when you really want it bad.

One way to fool your brain is by thinking next interview is what matters. Current one doesn't. So let's have fun.
Skills:
College Name: BITS Pilani
Motivation: Money
Funny Moments: Just didn't care as it was com sc. I was from EEE and I knew I would be rejected. In spite Of that, I seemed to just keep on sailing through one interview after other (5 total)

Remember later to over analyze and brood whole evening all little mistakes that I made in interview and wrong answers etc. only till end, friend calls, I am in.

Round: Test
Experience: Round 1: Online coding and aptitude test Section
Total time : 60 minutes
Questions{Marks} = 50(+1,-0.5)
Comments : * A few questions on Permutations and Combination and general aptitude * A few questions on Computer Networks and Operating Systems * Many C++ output questions, mainly on OOP * Questions are quite stimulating and these need proper time management, the idea of the concepts need to be at the tip of the tongue ("literaly")
Section 2:
Total Marks : 150
Total questions : 2 ( 100 + 50 )
Programming Languages allowed : All common PLs
Platform : HackerEarth Questions are easy but may require long codes. The output should be properly formatted.Not much algorithms Some 30 people get shortlisted for the interviews, consisting of maximum 4 rounds ( 3 tech + 1 HR).All interviews are elimination rounds

Round: Technical Interview
Experience: ( Tech interview-1):
* Mainly questions on the knowledge of C
* Trust me, one must be really an expert in C syntax, and you must know in and out of C
* Questions on pointers and bit wise arithmetic asked
* Some questions on Operating systems also asked( and these were really thought worthy, like how are interrupt handlers stored )
* Some resume based questions
(Tech interview-2) : Some 15 were shortlisted
*Mainly questions on algorithms
*Really tough questions , on trees and arrays, almost in the Microsoft level
*Should be optimized as possible.
*They describe one of their product, and then ask questions on how to solve some problems.
(Tech interview-3) Some 6 were shortlisted
Selection Procedure
* Interview by the Citrix India R&D Vice-President of Tech division
* Involves mainly resume based questions
* Most questions on Networks and TCP/IP
* Puzzles are also asked.
* You may get chocolates also in this round

Round: HR Interview
Experience: If you get here, it means you are 90% selected(unless you screw it really bad, by saying things like you don't know the company,etc ) *Standard question - Why Citrix ? *They mainly discuss what profile will be offered, and about the compensation and so on.

General Tips: I don't think I have any. In fact I had no aspirations initially to get into this company.In fact I too came to know about the company on the day I got selected into it :p
The only thing I can say is practice. Strengthen your networking and OS concepts Even though you don't need to be in the leader board of CodeChef for this company, you may want to know decent coding, atleast to make it to the interviews.
It was challenging and equally rewarding. I felt that this was a really friendly interview series, and they are quite accommodating and flexible in their questions. Infact even if you miss a question or two, don't worry.
Skill Tips: Forouzan - Data Communication and Networking ,C++ by Djarne Stroustrup HackerEarth and HackerRank Coding Focus more on Networking and OS if you want to get into this company, they don't focus on much of algorithms, since they don't want coders since it is a R&D profile.

College Name: NIT WARANGAL

Round: Test
Experience: There were 2 rounds  of Aptitude Test. The first was 1 hour and written by all students who had applied and cleared the required CGPA cut­off.  It consisted  on questions on the topics of Quantitative Aptitude, Logical Reasoning  and Technical knowledge in C programming. 25 students  were then shortlisted  on the basis  of their  performance in the first Aptitude Round  for  s  second round of written tests. This  time the paper was of duration 1 hour and required coding solutions for 3 problems  in the field of Data Structures using the C/C++   language.   The  questions were fairly simple and should not be too much of a problem if you have done Data Structures.
Duration: 120 minutes

Round: HR Interview
Experience: 14 students  were short listed  for the round  of Personal Interviews  on the basis  of their performance in the second round   of   written   tests.   There   were   4   panels   taking   interviews   simultaneously.   The   questions   asked   were   pretty regular.   Apart  from  your   coding,   do   keep   a proper   knowledge  about  the   theory   too,  for  eg.   advantages   of   Object Oriented   Programming,   definitions   of   Friend   Functions,   Overloading,   Polymorphism,   the   different   kinds   of Inheritance,   etc.   A   few   questions   on   Coding   and   Time   Complexity   were   also   asked.   Some   students   were   asked questions   on   Unix   and   the   Kernel.   Basically   you   can   make   the   interview   go   in   the   direction   you   want   by   naming subjects that you are well versed in and confident about, when asked to do so. Students   did   not   make   the   cut   were   told   so   immediately   after   their   interview.   At   the   end   of   the   first   round   there were   just   5   students   left   for  the  second   round.   The   second   round   saw   3   people   taking   the   interview   together.   It involved questions on Operating Systems and Data Structures. Not very tough, but requiring   some amount of thought.

Round: HR Interview
Experience: The HR  interview  was  only a formality,  and  took  place I guess only after they were confident that the student had made the cut. It was just to have an informal talk and inform the student about the result. The procedure was a fairly nice experience and transparent. After all the rounds, they selected 3 students as finalists from NIT Warangal. The company went around the country and selected finalists  from other colleges  in a similar fashion. Then the results  were finally announced 10 days  later and 2 students were selected for the job from our college.

Skill Tips: Be   thorough   with   Data  Structures,   Operating   Systems.   Take   the   name   of   any   subject   only   if   you   are   confident   of your knowledge in it. Be confident,  and make sure that you think out loud when trying to  answer a question.  Apart from   your   final   answer   they're   also   looking   at   your   thought   process.   So   even   though   you   don't   give   the   correct answer, you might just end up impressing them with the way you approached the problem. Also  I strongly believe that you can make an interview go  in the direction you want. They only ask you questions  in subjects  that you  tell them.  So  be very careful about how  you answer the question "Which is  your  favorite subject so far?" or "Which subjects have you studied?". A casual answer might just catch you off guard.
Best of Luck!
College Name: NIT WARANGAL

Round: Test
Experience: The type of questions mainly comprised of aptitude, dbms, data structures, operating system, object oriented programming, networking and few basic questions on C programming language.
Tips: For Object Oriented programming  the book entitled as THINKING IN C++ volume 1 by BRUCE EKEL proved to be very useful.For C, read Dennis Ritchie thoroughly atleast twice.
Duration: 60 minutes
Total Questions: 45 or 50

Round: Problem Statement
Experience: The questions didn't make use of any tough algorithms. The solution too was quite simple but on the contrary there were several test cases which we generally overlook.
Tips: Sometimes practicing tough questions, we stumble across easy ones, so always start learning things from the ground level. Stay calm.

Round: Other Interview
Experience: It was managerial interview and i expressed myself in the best way i could . The interviewer tried to trap me in my own answer but somehow i managed to satisfy him by my answers.
Tips: Stay confident and be yourself.

Round: Technical Interview
Experience: Initially, i gave naive approach to the solution but the interviewer gave me sometime to improvise the solution and i ended up with solution with log n complexity.
Tips: Practice coding questions based on Data Structures as much as possible but look at the solutions only after the exhaustive attempts of self trials.

Round: Technical Interview
Experience: This round was bit tough . To answer the questions on semaphore, you need to have very basic knowledge of the topic.
Tips: System programming book by Richard Stevens provides deep insight of the concepts.Have strong grip on subject knowledge too.

General Tips: 1) Once you kick off a start to practicing coding questions and understanding the concepts, you actually enjoy things.2) Group Study plays a very crucial role. Discuss questions with your friends and your seniors.3) If initially you get bulk of errors in programming questions , don't get disheartened .Try to run the program by compiling each and every line thoroughly and eventually you will end up with successful compilation and that happiness is priceless.
Skill Tips: Have a command on your domain.
Skills: programming Skills, communication skills, Skills to handle the situation.
College Name: NIT ALLAHABAD
Motivation: A software company with software engineer profile  and a good package too and both of them defines my field of interest :P
Funny Moments: when the result was declared with me and my friend both got selected, we both started jumping and crying aloud infront of everyone out there.And at the end when we were given chocolates , there was another box containing t-shirts ..and i was constantly looking there in the hope that soon, we would be given t-shirts too but to the dismay the handed all of them over to the third party :(

Round: Test
Experience: Written Tests:-

There was a 1 hr aptitude test & 1 hour coding round. The aptitude test had simple questions on c/cpp, Networking, OS etc. and some general quantitative aptitude questions.

The coding round had 2 questions to be done in an hour.Q1: A matrix of 1s & 0s are given, you have to find no of groups of adjacent 1s. Adjacency was based on 8-connectedness. (Finding no of components in an undirected graph) (Islanding problem :- -----/)Q2: A number is given and you had to translate it to string form (Indian system – lakhs, crores etc. not millions, billions etc .) The word “and” had to be added at the appropriate place (after 100s place if there was a digit in 10s or 1s place)

101 => one hundred and one

2311 => two thousand three hundred and eleven

900020 => nine lakh and twenty

35 => thirty five

3 => three

1<=N<=999999999

Round: Technical Interview
Experience: He took a glance at my resume and said “I called you because I liked your resume very much”.

I smiled and my confidence level skyrocketed to 200%.

He asked me to describe myself in 5 mins and started a timer of 5 mins.

General Tips: Tips/Advices:-They were mainly looking for guys who had done lots of projects in software. In the whole interview process they only focused on my projects and fundamentals of java. They didn’t ask me anything that’s not in my resume. So&#44; Don’t write anything in your resume that you’re not confident about. They just want you to have sound basic concepts.
