Interview Preparation Tips

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.
