First there will be a Written test in which the aptitude skills will be tested. Then there will be a GD round after which there will be a technical round and after that there will be an last HR round. MY TECHNICAL INTERVIEW (ARICENT) Interviewer: - Hi, myself Javed. Me:- Hello sir!!! Interviewer: - So Himanshu tell me something about yourself that I can’t read from this form (Form filled up by me after clearing the written exam).

Me:- Sir, I’m a hardworking and fully devoted to work kind of person. Interviewer: - Good to hear that (with a smile on his face). Now tell me something about yourself, which I can read from this form also. Me:- I’m a computer science graduate from P.G.D.A.V College, and done my 12th R.K. Puram in science stream with biology. Interviewer: - oh!! Bio!! It was too tough for me.. Me: -Sir it’s same like computer science, you just need to remember some interrelated terms. Interviewer: - hmmmm, Lets now comes on to the computer science. Me: - Yes sir. Interviewer: - So, what’s your favorite subject? Me: - Actually, I don’t have any favorite subject, rather I have a favorite stream with OS and Networks as the subjects.. Interviewer: - oh!! Good. What is an OS? Me:- Interface b/w user and the hardware. Interviewer: - dispatcher? Me: - dispatches the program from ready queue to CPU. Interviewer: -Process? Me: - an active entity, whenever a program is in execution state, it is called a process. Interviewer: -Thread? Me; - it’s a lightweight process, contains only few… Interviewer: - (interrupting me in middle) you look quite confident in your answers, but why your written was so poor? Me: - cause I was confident there also. Interviewer: - hmmm over confidence??? Me: - No sir, confidence on your wrong answers is not called overconfidence; it’s another kind of confidence. Interviewer: - (smiling) Do you know that I’m the most lenient interviewer out of all who came here. Me: - don’t know sir, till now I’m feeling good Interviewer: - (coming back to OS) what is kernel? Me: - main part of OS, which directly interacts with the hardware. Interviewer; - what does an OS do? Me: - process management, memory management, file management, allocation of resources.. Interviewer: - (Interrupting again in b/w) ok, ab thodi programming kar le?? Chhote program se start karenge.. Me: - Programming?? Ok sir, But I must tell u that I’m not that good in programming, but I can certainly make an algorithm of any program u want… I’m quite comfortable with my algorithms. Interviewer: - You are comfortable with your algorithms?? Good!!! But I expect u to make programs also… Me: - I’m not saying that I won’t, I said I’m not that much good in it. Interviewer; - par 1 to bnana padega yaar, chhota sa bna do, Kaunsa bnaoge?? (Answering himself) string copy ka program bna do.. take your own time.. Me: - k sir.( He went outside and came back in five minutes by that time I completed my program).. Interviewer: - you are comfortable with your algorithms na??? Me: - (confidently) Yes sir Interviewer: - quickly make a algo for BST Me: - k sir!!! It took hardly 2 min to make it. Interviewer: - After analyzing it, what is running time of an algo? Me: - Of this particular algo or you are asking in general?? Interviewer: - In general. Me; - its basically tells about the memory usage, time taken to run it independent of the system. Interviewer: - runtime of bubble sort? Me: - O(n2 Interviewer: - runtime of quicksort? Me: - O(nlgn) for average and best case and O(n2 Interviewer: - what is the worst case in quicksort? Me: - when after positioning u have all the elements on one side of the pivot element.. Interviewer: - I think this is the case when all the elements are sorted. Me: - (smiling J) oh!! Yes sir. Interviewer: - ab computer networks par aa jaye?? Me: - Yes sir!!! Interviewer: - ok, tell me the protocols in each layer of TCP/IP Me:- for application layer:- its HTTP, FTP For transport layer: - TCP, UDP… Interviewer: - (interrupting again) difference between circuit switching and packet switching? Me: - in circuit switching we use to make connection b/w source and destination, and start transferring the data, in packet switching, we send data in packets and connection is not dedicated initially, In circuit switching.. Interviewer: - (interrupting again) example of circuit switching? Me: - (thinking) telephone. Interviewer: - (interrupting again) example of packet switching? Me - Internet Interviewer: - ok Himanshu, Nice to meet you. Me: - Same here Sir!!!
