      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.

        Group Discussion

        Interview Experience
        GD: Just starting each time or summarising is not sufficient. try for best.1. Just speak twice but such that none will talk at that time. i.e. everyone will listen you.2. Just keep on shaking your head to show your listening and agree with him. so at your time he will certainly listen you.3. If everyone try to speak making fish market then just keep on speaking "friends please calm down, it's getting fish market. try to speak one at a time. plz friends plz"4. If someone wants to talk but not getting chance then raise your voice n say "plz, one of our friend also want to share something"n then point your hand towards him (not finger)5. Try for start and summarise (yes for both) if not possible them minimum secondly.I really used this at last n got placed on same day. I edited my resume n entered like "Completed Basic Course of Art Of Living (this was fake), Certified course of discover yourself (i had certificate)" and i was asked about that only in interview and got selected in CisCo....BEST OF LUCK (with confidence)

                      Interview Experience
                      I studied c, data structures since it is compulsory for most of the companies. Went through one or two previous years papers in the placement web site. Just before the day of the test I went through the digital and microprocessor basics.

                      There were two profiles; Software and Hardware. We had an option to write both the tests, so i took the software and then hardware (I was not at all serious about hardware). The aptitude section was common to both the profiles, which is comparatively easy. Some questions were repeated from the previous year’s question paper which was given in the placement website. The questions in software profile included digital, microprocessor basics and some general networking and operating systems qns. As I remember correct, surprisingly there were no C, Data structure questions. But it is always better to expect c, data structures in every placement test you write. In networking, IP address related questions are so common that you will find it everywhere.

                        1st round: was everything based on your resume. If you can impress them in your first round, you are half way through. They started from simple questions but finally ended up in my research work. I had to defend my work like anything.

                        2nd work: Puzzles, C, data structures: It was the simplest round. They look at the way you think.

                        3rd round: Networking basics questions. Some of the candidates did not have this round. It could perform only in an average level in this round (may be below average too :)). I think they do not expect much of the networking knowledge from you. Otherwise I wouldn't have got through.
                        Round 3

                          No worries in this round. Be yourself and answer naturally. They asked something like if a conflict comes, how do you deal with it? etc.

                            The presence of mind and the way you defend your project is very important. I mentally prepared on how to present my research work and projects. Networking basics. I stayed calm.<br /> <br /> Prepare C, data structure foe all companies. Communication Network helped a bit in networking.Common subjects will help in QUALCOMM and Broadcom. If you are aspiring for finance companies, prepare IMO questions.

                                  I have no idea on how they shortlisted students for written test. For the interview, it was based upon our written <br /> test performance. Since they came on day 3, they had a waiting list of students for the interview.<br /> <br /> <br /> Started solving previous year question papers. Almost all companies follow the same pattern which they had in the previous years. You might even get the same questions. Start solving puzzles and previous year question papers from August. There would be flurry of companies coming for CS and it would be very difficult if one starts preparing late. Earlier the preparation the better.<br /> <br /> Important for CS students: C, C++, Data structures and Algorithms, OS. <br /> <br /> Few companies ask students to write programs on paper. The best way to prepare would be start solving <br /> programming questions.

                                  It would definitely help students if they start their preparation by August.

                                  Asked about interest . I answered algorithm and data structure . Then started questions -Asked me to implement Stack and write a function popMin() which will give the minimum value from stack in O(1) time .Given an input file and two input words , find the min length text segment from tht file which starts from one word and ends at othr . My code was nt handling some test cases , so he corrected me .How google suggests you words when you type some spelling mistakes .Told him about Levenshtein distance , but then he asked me how probability theory is used in decision making  when the distance is same for more than one word . I made some guesses . Told me to implement Levenshtein distance .Asked me to design a unique identifier number . I used diffrnt things to make it unique but he was nt impressed . Finally he gave me hint : ”The thing which never comes back when we loose it ” . I answered TIME . So basically he wanted  me to use time for making number unique .You have to design a LRU CACHE such that all operations can be done in O(1) – read, write and insert . No code just algo n DS to be used .An array(sorted ) is rotated , write a function which takes an input array and returns the no. of times an array has been rotated .

                                          Watched a few mock interviews (Youtube / other websites). I also went through some books which covered common interview questions. Electives and course work details were not considered for shortlisting. My MS thesis is in the area of Wireless networking. It helped me to convince the interviewer why I was interested in working in a networking company.<br /> <br /> I initially focused on aptitude, then Programming / Algorithms and data structures.
                                          General Tips
                                          Two-Three weeks before the first placement test. For communication companies, I refreshed digital communication fundamentals. Basic of linear algebra and probability theory. Also, spent some time, studying the basics of data structures and algorithms.



                                          One should be prepared to explain every detail in his/her resume. Most interviews start with the description of one's project work. For both core (communication) and non-core companies, programming concepts (C and data structures) are very important.

                                                      Good CGPA definitely helps. But systematic preparation is most important. Don't neglect aptitude. Practice it well before placements. Go through previous papers of the companies. In interview, questions follow from the answers you give. So be careful while answering. Don't bring in something you are not clear about.
