4 Interview Rounds
Interview Preparation Tips
Round: Test
Experience: In written the questions are from aptitude,reasoning,computer organization,basic electronics, networks,operating systems and few questions on c. In apti questions are from time &distance, alligations & mixtures,etc.,. In reasoning questions are threoritical. Good questions came on probability,permutations & combinations,set theory. In C0 ,logic gates,number representations,complements,flag bits,etc and in electronics questions like zener diode,rectifiers ,etc.,. and then in OS questions are from memory management,disk scheduling,semaphores,etc.
Duration: 60 minutes
Round: Technical Interview
Experience: In technical interview the questions are from DS,OS,C and Networks. In DS they asked me to write codes for linked list reversal, deletion etc and then on trees for insertion, iterative codes for traversals. Then on hashing he asked where you use hashing how it is implemented,why you use that and then various collision resolution strategies. Then he came to critical section and about synchronization, semaphores, FIFO, pipes, differences between them etc. In OS he asked about CPU scheduling, preemptive, non preemptive, context switch etc. Then he came to cpu registers and then to various storage classes in C, he asked me by taking various cases how static and extern works. Then he asked me to write codes for some real world problems. In networking about the OSI and TCP/IP protocols and then about each layer in detail with various functions,addressing and protocols. He asked m some general questions on networking, about ping command, about domain name server. Then he asked me to explaining detail the working of TELNET and whole communication process.
Round: HR Interview
Experience: In HR he started with my academic details. And as iam from MCA he asked me the difference between technology and application. Then he asked actually what i am interested at,what kind of work i wants to do. and then he asked how you visualize yourself in few years and then how can you justify yourself with cisco.
Skill Tips: My suggestion is that you should be perfect in all subjects. prepare in your own way. Good command on all basics is must.

4 Interview Rounds
Interview Preparation Tips
Round: Test
Experience: Exam contained 50 questions which consisted Aptitude-20 and technical-30. In aptitude he asked some simple questions on math and English. In technical there are questions based on c(ptrs),os,networking and some ECE subjects which i dont know. No negetive marking.
Duration: 60 minutes
Total Questions: 50
Round: Technical Interview
Experience: In the interview, first he asked me for my favorite subjects I told him networking,os. questions were on arp, how to solve IP conflict in a system having for computers connected to a hub, some other questions on networking like what happens when we type URL. Some simple data structures programmes.
Round: HR Interview
Experience: Basic question tell me about yourself as I had edge in my technical interview hr round was quite simple, he asked just 34 questions like why not MS? Are you interested in networking? HR person just explained about the company and how company works etc.
Skill Tips: Don't neglect CGPA. It effects so much to certain companies. Keep good knowledge on OS, networking, C and DS. Be thorough with OS concepts. Study concept in the way of "how" and "why" it will develop subject.

5 Interview Rounds
Interview Questions
- Q1. What type of data structure used in windows search? i said may be B+ trees.i explained the theoretical part of B+ trees(y preferred over binary trees) and about...read more
- Q2. How PING works? ICMP protocol.so add ICMP header to ip payload field and stuff.
- Q3. Write code a simple program.(when he saw in my resume Datastructures written in bold ..so take care of it..lucky for me it was ds not some ece subject)
- Q4. Why CISCO?
- Q5. Any references?
- Q6. Tell about yourself.
- Q7. Explain me DS in nutshell. i mentioned trees,linked lists,sorting algos,graphs,etc
- Q8. How www.google.com typed in browser works??(abt dns server,etc)

Interview Preparation Tips
Round: Test
Experience: The paper had for sections.
1. Apti(regarding probability..time and distance)
2. Logical reasoning (a bit lengthy)
3. ECE related questions(1.zener diodes(working principle)..adc converter(no.of comparotors in 4-bit flash ADC).. 85. Can be represented 1n 4421code as??...regarding multiplexer)
4. Microprocessors:
i.given addresses find invalid address(constraints mentioned)
ii.next instruction stored in which register )
5. C concepts(what is the output for a pointer modifying a constant data variable (it can be modified) b.regarding int *const p && const int *p) OS..concepts in THREADS..(pretty good ones)
Round: Technical Interview
Experience: I answered as fast as i could.and in 5 min,i was explaining abt transport layer, starting from physical layer.
i explained them in 1. Datalink layer a.fragmantation(bit stuffing,etc)b. error control(crc,etc) c.flow control(1 bit sliding window,go back N,etc) 2.network layer (routing protocols, ICMP, ARP, RARP, BOOTP, DHCP). This is when he 2.asked me to explain ARP.i did that and explained why RARP is used. Whats it drawback. then why BOOTP..its drawbacks..then DHCP in transport layer(HE asked where UDP is used?Then abt connection setup using 3 way handshake release overcoming Army problem).
3.Explain PORT addressing? i did and explained abt IP and MACid too.OS:1.he asked me abt Round robin,SJF,FCFS. i explained how premptive round robin works. and how in schedular queue PROC stuctures get attached(doubly linked list way)..to this structure(queue) how premptive Round Robin works?2.Tell regarding CONTEXT SWITCHIING.(i mentioned about storing register values in Uarea,then proc area ptrs to scheduler queue changed,State in proc changed from running to ready to run,the next process PCB values got from pointers in scheduler queue>proc>uarea and mmu mapping)3. Tell about Critical section?(I gave an example regarding unsteady state in removal of node in linked list) and mentioned about semaphores,etc
Round: HR Interview
Experience: My 1st interviewer was technical guy but he was asked a few HR questions too.
1.why CISCO?(NETWORKING,os r my fav subjects.interest in Cloud computing,etc.perfect platform for fresher)
2.Why not go for Ms?(Noooooo..when i can get a job in R&D in cisco,Bang then y do a ms and try for a job at companies
like cisco abroad.[basically they r believe that cisco,india is as big Cisco,usa branch])
3.tell abt ur family.
4.did u apply for oracle?(cgpa cutoff was 8.0)[be honest]
Round: HR Interview
Experience: I had another HR round when i was at my home during winter vacation.
Tips: Don't worry abt the HR be cool. I got the news that i got selected a week later.
Skill Tips: For Cisco,CGPA is a very important criteria.a friend of mine was rejected just coz of his low cgpa. lucky for me when Cisco came,there were not many high ptr fundoos around. read well.i am good at ds,os ,networking.so understand ur strengths. For os read Galwin and refer uresh walia(unix )[everything i answered regarding os,is mentioned there] or bash for networking prefer ferozeon. but whatever u read ,read with dedication and be clear.Beware:they will try to confuse u. learn about cloud computing and stuff..only abt their use,etc. be patient. I always thought "mera number kab ayega". though my air AIEEE rank was 500+(5th in my clas)..my cgpa was low.. the recruiters clearly felt our CG's were low. at first they wanted to shortlist based on CGPA. I thought I lost another company on cgpa shortlisting basis. but at the final moment they changed their mind,and though over 7.5 were only 15 cse students..they didnt reduce the cutoff.CISCO cares for cgpa.if urs is low, try to defend urself by showing good grades in subjects they require like networking,ds,os,etc. questions asked to others: how hub functions?(must be sure of hubs,switches,bridges,gateways and their differences) how to ensure compiler optimizes inline functions every time(may be using #pragma) learn about DBX debuggers,epilogue in functions(advanced compiler stuff). activation records, AVL trees, SPLAY trees,use of Fibonacci heaps in Djstras(read weiss carefully) For other companies plzz dont ignore these things virtual functions(a must for ECE guys polymorphism,inheritance) refer "LET us learn c++ (yashwant khanitkar VIRTUAL functions chapter..and *this,Vtable,vptr..for full clarity) PAGING(page table types,page faults,thrashing) they ask about LOW pass filters,etc read morris mano..brush up some concepts..coz for PD(platform dependant jobs)knowledge of hardware(ECE) can be a criteria. i didnt get into Qualcomm,citrix,etc(all related to networking )..but finally got my dream job. lessons to learn from me.. take resume(hard copy)..reason for not getting into qualcomn. so take care of little things.
