Verbal
Find the Wrongly Spelt word
Synonym
Antonym
Fill in the blanks
Aptitude (purely mathematical)
- Better have a look at the previous 1998 qn paper, from that we got many questions.
- strong analytical geometric and mensurational skills needed.
Computer Awareness
- Simply like find odd man out and 10 qns regarding 2 pseudocodes given
Time Constraint was the big thing, u cannot complete the paper if u solve all the
qns, its not needed also, they're just seeing the relative mark, in our college from 150
, 29 were shortlisted for GD and from it 12 were shortlisted for Interview, i missed
out in GD.
Topics were War on Iraq, Leaders Born or Made
Try to assess ur group in GD, if u think its of to be an debating group, pls don't
follow GD rules, and create ur oppurtunities for speaking as raising ur tone,
intervening the conversation going on, 'its pretty sure that u'll be going off the GD
rules, but it was the case in our group", i followed GD rules and i missed it out.

Tips
1. Do the coding first and you are out - They are time consuming - Save the worst
for last
2. Be choosy - take the easy (questions) first - So scan scan scan
3. best path in hexaware tree
language ---->
odd man out ---->
computer awareness ---->
easy sums ----->
difficult sums---->
coding
do this or find the path to your home.
4.SPEED kills but also wins. Put your brain in 5th gear
5.Blind goose guess - mark a or e - they are more probable
6. Write your q paper code proper or your are a man overboard
7. There is minimum no of q to be attempted(so they didnt say explicitly) and no
negative marking. So be generous!waste your ink! cross off for all questions
8. They will ask u in the pep talk in GD waht is the first or last question or your
code.
So watch out all those DANGER-PAST-QUESTIONS-FORGOT type fellows
Group Discussion
1. No GD only shout!!! - Our LOk Sabha Style
2. Shout at top of your voice and shout some meaningful points
3. Please train ur vocal chords! Drink our good pure(pun intended) water before
GD
4. IF u cant then carry a loudspeaker
5. 10 per group max 3 groups
6. final interview they select 3 from each group

too.
8. If your group is silent Please follow GD rules.
9. 30 minutes of shouting(3min-choose the topic, 2min-prepare,20min-shout)

Wat I felt with this test was it was better to go thro all the 100 ques, cos some easy
ones were there at the last. If U think U can certainly solve a problem but its time
consuming just leave it and proceed to the next one. Some of the ques were very
easy, even U no need to use pen and paper.

paper had 48 questions to
be answered in 1hr. Time will be quite sufficient. They have different
sets of question papers. .

Ans: I don't remember the answer but first 2 are true.
5. Some quesion regarding the company and
who developed it ( the thing to remember is that Apple
produce Macintosh computers).
c/c++ section: questions on c/c++, programs
o/p etc.
1 main( )
{
unsigned int i=3;
while( i >=0)
printf( "%d", i--);
}
how many times will the printf stmt be executed?
a)0 b)3 c)4 d)infinite
Ans: I think the answer is infinite, b'cos 'i' is an unsigned integer
and it will not decrement below '0'
and hence end up in an infinite loop.(yes, i checked and it is getting
stuck in an infinite loop)
2. main( )
{
int x,y, z;
x=2;
y=5;
z= x+++y;

temp=0;
if( i > j)
swap( i, j );
printf( "%d %d %d", i, j, temp);

Iam really sorry for responding so late.
I wanted to sit with your work but I could not ( because of some problems )
I remember very little about the Dharma test pattern.
There was an Apptitude test. Quantitative and Analytical.
The Quantitative is very easy. You should prepare from GRE or any CAT
Material.
The Analytical part is mostly from Barrons Guide. I remember two questions .
they are from Barron's guide. It is something about a village called "kaya-kaya
" where half the people speak truth and half lies. There was one more about set
of houses of itallian,germans,romman etc in a row whose chimmney colours were
given, their favoritr drinks were given. I hope you will find these questions
in Barron's guide. I did not get a Barron's guide to search them for you. The
interview was mostly about C , C++ . They are mostly working on C++. That will
help if you know. They are working on their own SQL. You should brush up your
fundas in DBMS. In interview there are questions in UNIX Internals also. Hope
this info is of some use to you. Good Luck. Keep me informed on the proceedings
of the campus.

Regarding Hughes
paper they conducted two tests. Both were technical(no aptitude test).
First one was compulsory for everybody. In second one could opt for
electronics or computers. In all i suppose there were 50 questions.
I sent a request to my classmates to send me questions whatevery they
could recall. Till now only one person has responded. I am sending those
questions to you.
And just before interview you were supposed to fill up a performa which
they call Behavioural Test. This was to check you interpersonal skills and
socialising capabilities. Questions like - would you like to be elected
leaders of organising committees, do you like peoply express their agonies
to you, do you wish people be close to you type questions were repeated in
one and the other form.
Interview was technical as well as personal. CGPA did count - it seems.
They selected 8 people from here. BTW what's your current CGPA and what's
the strength of your class. Do they come for B.Tech and M.Tech separatel
as the case here is or it's all at once.

Top 10 Interview Tips OF Hughes:
================================
Here are the 10 most commonly asked questions in the job interview, which will
help you prepare yourself better for the forthcoming campus placement and also
give you a competitive edge over others.
A well thought out answer to these questions, prepared and rehearsed in
advance with the logical sequencing of the events will help you sail through.
1. Tell us about yourself
This is an open canvas for you giving you an opportunity to direct and lead
your interview in the direction you want. Good idea will be to structure your
answer in the following three broad heads:
Family Background
Educational Background (starting from schooling to
professional qualifications)
Achievements
In all the above subheads speak only that information which will give strength

Interview tips-
==> 1.Family background.
==> 2.Ur interest.Say only the things u know.Sometimes they can
ask wayward questions regarding ur project so be prepared for that.
==> 3.U should have fair idea abut the sub. mentioned in ur resume.
==> 4.If u don't know anything say NO.
==> 5.Try to get stuck in the topic which u know thoroughly.Like
one of my friends got stuck in tcp/ip networking and he got thru.
==> 6.In our college four groups were taking interview so some of
us were unlucky as the judgement varies.
==> 7.Why do u want to join hughes.For this get the answer from their ppt.
==> 8.If ur given a project in some other field would u work.Say
yes i would try to succeed in every task assigned to me.
==> 9.They can ask u to write some algo in datastructure like bubble sort ,quick sort etc.
==>
==> Mostly the technical questions varied from person to person
but generally was concerning their project.Unfortunately they asked m$

About hss - for us
the interview was basically on summer project , networking - routers /
congestion control in tcp etc, some os fundas .HR part was a modified
version of the stuff on the web site - strength/weakness,can u work in
a gp, do u have problems asking ques to ppl, ur future plans , gre .
i think i didnt get it bec. i told them that i plan to do an ms.

there are 20 questions all in techinical paper and 36 questions in appititude te
st
in appititude thay have given all diagrams and asked to find what comes next
thay are quite easy and i hope if u practice r.s aggraval u can do it easily
for tecnical thay have given 1 hr for 20 questions and for not technical thay ha
ve given only 40 min
and 36 questions
this is the paper i have right now
1. main()
{
fork();
fork();
fork();
printf("\n hello");
}
How many times print command is executed?
2.main()
{
int i,*j;
i=5;
j=&i;
printf("\ni= %d",i);
f(j);
printf("\n i= %d",i);
}
