Round: Test Experience: The Technical Part of the written test was divided into 4 sections - Programming Ability, Data Structures and Algorithms, Operating Systems and Networking Concepts, and another section on a Programming Language (choice of C, C++, Java). The Quantitative and Reasoning questions were mostly simple questions like interpretation of bar graphs etc. The tougher part was the technical section. Duration: 137 minutes
Round: Technical Interview Experience: I had two rounds of technical interviews. Both the rounds lasted around 10 minutes each. The questions were mainly related to my research projects and my research paper(in Data Mining) in particular. I was asked in-depth questions regarding the implementation part of my research paper. Other than that, I was asked basic questions in Data Structures and Operating Systems. On the whole, I felt my research work played a crucial role in my technical interviews.
Round: Technical Interview Experience: The interviewers in the technical rounds were very polite and they tried to bring forth the best in me.
Round: HR Interview Experience: My HR interview was the longest and toughest interview. It was a bit more strenuous as interviewers tried to see how I would react under pressure. It lasted for around 40 minutes. I was asked various questions about my career goals- "Why HP?","What would I do if IBM offered me a similar job?", etc. I was also asked to talk about the core values and principles that were important to me as a person and how a job at Hewlett- Packard would enable me to realize them. I answered the questions candidly and confidently, and justified everything I said with rational arguments. Tips: In the HR interview, be straightforward and answer confidently.Study the basics of Data Structures and Operating Systems thoroughly. But,be prepared with other important subjects like Systems Programming, Compilers, Database Management Systems, and Networking also. In the technical interviews, try to focus on your strengths(like research projects, internships and any other academicachievements).
Round: Test Experience: Out of 50 people who appeared for the test, only 5 people were shortlisted- 2 from cse and 3 from ece. SEC 1: 20 questions on quantitative ability. It consisted of questions on cubes, logical reasoning, sets, venn diagrams, 'statement 1 is correct or statement 2 or both' type of questionsSEC 2: There were questions on data structures and file commands like rewind,fseek etc..SEC 3: There were 15 questions on operating system concepts, unix commands and networkingSEC 4: There were questions on overloading,object oriented programming, pure virtual function, inheritance, pointers. Duration: 120 minutes Total Questions: 75
Round: Technical Interview Experience: They asked me lots of questions on c, pointers, questions like what is volatile, register, extern, macro, inline function, typedef, enum and static const char* const*char difference.Proper knowledge of c is very essential.Then they asked data structures questions. Those were very easy.Then they asked me bytecode in java how and where it is used, java virtual machine functionality, why it is platform independent, padding in structures....then they asked about real time operating systems...unix and real time what is the difference, what is the scheduling algorithm used in unix and windows, in which operating system priority scheduling is used...what is memory leak, when do we get segmentation fault...what is semaphore, ptherad mutex, what is leakymemory, fork system call how is address space copied, what is 3 way handshake protocol, ipsec, digital signature, rsa, public key cryptography, If you have100 mb RAM, how will u write a program so that the system crashes? Just allocate with malloc size greater than 100.
Round: HR Interview Experience: General questions were asked. Like, where r u from? Why do u want to join HP?What achievements have u done to prove that you are good at coding...i don't know why companies ask this question...I guess they are looking for someachievements...Then he asked me where my dad works and general HR questions. Tips: Communication skills is essential.
General Tips: If you are interested only in package only then don't sit for HP. You might get a higher package in a new company but the problem is that it might not send you an offer letter or make you sit on the bench just giving you salary, which automatically increases the chances of sacking u. I got my first normal job around august when the placements initially started but then after a long time of wait. I sat for about 12 to 13 interviews and got rejected in all of them.So please do not lose hope. Wait for right opportunities and grab yourchance and do not get frustrated. College Name: NIT WARANGAL Motivation: HP has a brand name. The work profile for me is R&D in Image Processing. Though the pay package is less, if you perform well, you will definitely get a hike.
Round: Test Experience: Test was conducted by a consultancy, so they gave all possible types of questions about C,DS,OS,networking. Duration: 130 minutes
Round: Technical Interview Experience: They interviewed me about 2 hours which includes two technical rounds and one HR round. They asked different questions related to c like 'where will the returned value go from the main', about segmentation faults and regarding segmentation, virtual memory, recursion and they asked me to write a program for towers of hanoi,and a few definitions from c++ like inheritance, polymorphism, abstraction . Tips: Maintain smile on your face throughout the interview. Just keep your head cool. be thorough with C,C++ and DS. ECE students be in touch with CAO concepts and C questions.
Round: HR Interview Experience: They asked me about myself and my family and my recent achievements. They gave 60 cards related to different aspects of life and asked me to choose any five with which i can sustain.
Round: Test Experience: There were five sections in the written section. The first section consisted of c algorithms, second section was of quant type (pretty easy), the third section had a mix of c and data structures questions, the fourth section comprised of questions from os and networking and in the fifth section students were given a choice between c,c++,java. I opted for c, the questions in this section were of very high standard. Then there was an English section in which we had to write a letter. Duration: 150 minutes
Round: Technical Interview Experience: They shortlisted around 23 students for the technical interview. Depending on your performance they kept shortlisting students in the interview itself. My first interview was pretty easy. It comprised of questions from c, oops and codes were asked from ds. The interview lasted for around 45 minutes but was a pretty easy one .
Round: Technical Interview Experience: Once I was shortlisted for the second interview, i had a difficult time facing the second interview. The interviewer kept asking questions from networking to which i had no clue as we are taught networking only in 4-1. Then a few questions were asked from os (semaphore,deadlock,fifo,critical section,thread), then a few questions from cao as i had stated that it was my favourite subject. The interview duration was around 30 minutes.
Round: HR Interview Experience: In the HR interview i was asked 3-4 puzzles (pretty easy..practice some from any puzzles book). Then they asked me questions regarding my strengths, weaknesses, passion, why hp should hire you?, and so on..pretty cliche stuff. The interview lasted for around one hour. Tips: Once u get through the technical rounds you get pretty sure that you have landed the job, but we should never commit the mistake of taking hr interview lightly. The only thing that matters in HR interview is to be confident in your answers and never to back out on any previous answers that you have given.
General Tips: Be thorough with your concepts in c,c++,ds ,os and networking.c must be your strong point in order to clear the aptitude. Choose another subject to be your favourite and make sure you are thorough in that subject. College Name: NIT WARANGAL
Round: Test Experience: in the technical written test, there was a paper on C programming. it had general C questions which were of the type>find the output,error etc there was another paper of Data Structures which had some theory type question and some output finding questions there was a paper on Operating System which had 20 questions. all were theory type questions the entire paper was objective type paper. Total Questions: 150
General Tips: I was confident in the entire procedure and that made a difference. I answered every question with confidence even where i may have had doubts. In the end i got through and it made a difference. also another thing i would like to add is that the written test was conducted by some external agency on behalf of HP.my suggestion is that prepare C and OS well. and be confident while facing the interviews. clearing the written is the difficult part but once the written is cleared, it all depends on how well you can communicate your ideas to the interviewer.
