From My Memory.......[6th Dec,2010 ]
Hi friends,
I have never tried to write
any experience of my life.. and I never try to write a diary in my life. I
wrote the last paragraph in my life in final exam of higher secondary. As most
of my friend request me to share my experience of my interview , I m trying to
write something about my interview. Today is 6th dec, 2010, at
2:15 Am. I am trying to re-visualize the
event occurred in that night and try to give perfect sequence occur of event
of my interview.
I am in M-tech 2nd
year student ,IIT roorkee , our placement started from 1th decbr , Citrix was the
5th company in our campus. I m not able to clear the written test of
google, adobe. I cleared the written test of Microsoft but debarred in GD in coding. I have cleared the written test ,
first round interview of Netapps but they put me in QA rather than DeV
group..and in the 2nd level of interview they discard me as i was not interested in QA positions ...
In 4th
December, there was two back to back interviews, first one is Netapps, the
interview process is so bad .. I cannot tell u. they call me at 12:30 pm and
take first round of interview and the took 2nd level of interview at
6:45 pm … in fact they harry up the interview process and leave me at 7:00pm ..
I did not feel any depression because from next was Citrix , which works on
same domain of mine, in Cloud Computing..
Citrix had 4 level of
selection process:
First level written
test started at 7:15 and a duration of 1 hours, it fully consist of c question(
basic on c++ from test your c skill )
there was 50 questions. No negative marking. Some simple apti.(every 10 th
question. They prepare the question well formatted and they gave color full
question paper, by chance I got a yellow color question paper.different color
indicate different sets to restrict copying…
In
second level , there are 3 coding in paper and pencil:
Q1.
Write a program which marge two sorted single linked list into single sorted
linked list it must remove duplicate..
This
one is very simple ..and already known to me.
Q2 write a program which find LCA of a binary tree. It is not a BST.This
problem can be done by simple recursion and also known the logic previously
Q3.
Write a program which print all possible combination of 10 A and 10 ‘B’.
This
problem was unknown to me.. but a little though give me Good idea to solve this
problem using divide and conquer rule to solve this problem,
They
gave 1 hr time to write the program.
I
solve each problem in a good coding fashion and after each problem I gave a
illustration of execution. I have also properly handle the exception. I took
near about 40 min to solve the problem.
I
asked them when the interview will be ? they told me at night.. but I was so
tired that I directly came back to my hostel. I had already missed my lunch
and dinner both. Took a bun omelet from canteen and went to sleep. I was sure
that I will get a call for interview. Thus before sleep I told amit to awake
up if I was selected for interview. I
know that my prediction fail a little.
As
expected, I got a call for interview directly from placement cell at 12:50Am.
They told me that I got selected for interview and the to come to placement
cell with in 15 min. some of my friends also got selected and just ware the
dresses and come out from the room.
The
night was completely silence…cold and some dogs are sleeping outside the gate..
I took my ear cover( just like headphone) to save me from cold. I was very
cheerful and cool because I know there would be lots of fun going to happen in
interview. I
was not felling sleepy.. in fact I have good (?) habit to sleep late night at 4-5
am.
After
reaching the interview placement cell , I found that 17 people are called from
Mtech , Btech and IDD, I m also feel some nervers. After thinking , there are a lot of companies like
Oracle/ Yahoo/CISCo still there… but I not able to cool at that time…I just
sit in front of hitter and njoying how other people preparing for interview.
One of my another habit is that I never read or try to recapitulate something
just before interview.. again I am trying to sing some Bengali Band song in my
mind….i started observer how the heater works.. how it was rotating and related
to hitter….really I didn’t see this type of hitter even before…
There
ware 3 panel .. so there are three parallel processing going on…my name was top
3 from the bottom of the list.. I understand that each of taking 30-45 min then
my term will come near about 4:30. I fell boring .. how long a person can observe a hitter?
I
found that Btech people take it more seriously ,, collect and discuss the ans
within themself. but Mtech people are are most caz.. our topper avisek sleep
in chair ..shib also do so.. told me to wake up when there turn come..interview
process was going on…
One
of my friend Tonmoy brought tea for us.. after some time I just go through my
resume.. try to every thing I stayed about cloud computing.. and just took a
look over my recent published paper on cloud computing on IEEE symposium, Bangalore.
I decided to take tee to take my energy . I put tea into a cup…and just ready
to take tea…my term come….anyway I have to leave tea.. and go for the next
Fun…. Now this time I feel some kind of something ..i cannot express .. but I
understand my heart was beeping and I was vivarting…was this a effect of cold ?
or something else ? J
It
was 3rd panel. There ware two persons.. one middle age person
,looking scientist and other was young
looking very smart. After welcome notes. They asked to tell something about me.
After that they introduce themselves. One of them was some higher post engineer
in Netscalar , acquired by Citrix, and other was working on desktop
virtualization,:
First
question was:
Lets
there is an array A[10];They
wrote some code something
Int
arr[10];Arr[0]=0;
Arr[1]=1;
-----------
Arr[9]=9;
Printf(“%d”,a[15]);
What it will print? And why?
I
gv the solution and also give the backed logic to support my ans.
- Next
question: explain your work on scheduling.
- Next
question: why genetic algorithm?
- Next
question: what is virtualization? What is the advantage of Virtualization?
- Next
question: give some example of real application of virtualization.
- Next
question: what are different type of virtualization.
- Next
question: what is the difference between traditional computing and cloud
computing.?
they
look my dissertation topic and ask what is difference between traditional
license management and license mangemeant in cloud computing?
Next
question: how to determine is there any loop in
a single linked list or not?I
clearly state that this is a known problem to me.. they smile.. and say.. can u
prove the correctness of the algorithm what u know.I
proved by inductionThey
make it more complicated.
If slow pointer increment by 2 and fast pointer is
increment by three then do u think it will detect the loop? Prove correctness
of algorithm, which is more efficient and way?I
say that 1st one is more efficient.. but they show some counter
example. Really it depending on the length of
SLL.
They
switch to next puzzle: in google, when we type a string to search . how will you find top
most 100 search text in most efficient way.
I
give 3 alternative solution and explain them and also tell them each advantage
and drawback.Approach
one: Hash table + Max heap treeApproach
II : trie structureApproach
III: augmented BST or Red black treeThen
they switch to networking:They
ask three simple question from networking:
- Q1.
Explain what ‘s happened when we type something in address bar?
- Q2.
Explain what is fast retransmit and what is advantage of that.
- Q3.
How flow control is done by TCP?
I
say I m not sure about this ans. But I guess the ans : fortunately it was
correct.. it’s selective ACK.
My
interview then over . they ask . u have any question ?
I say that I was not able to attend the ppt
due to my workload. Can u kindly tell me something about co0mpany ? what type of
work currently is going on in your company ? and whether phd is offered by your
company?
They
answered . and thanks me and tell me wait for next level of technical
interview.
I
come out from the panel.. felling very confident as my interview was quite good
.. again the some thought came into my mind.. if I wound not select ..then why
to worry? Anyway yahoo is coming today !!!!
IT is 5:15.. it’s horrible cold… and we are 19 peoples are playing with dr luck….the
silence take over the whole IIT( definitely it is not HIT , in HIT the scenario
is quite different :) ). And after that we wait for half hour with cold bez I m not
not allowed to those person who r not still not appeared for interview.after the
some time the list of selected come .. only 3 person was selected out of 19 ,
and I was among them. They told other people can leave now.. my friend wish
best of luck to me and go to hostel.. only my M.tech peer with me.. they
told that no 2nd level technical interview.
Just there is a HR
interview.first they called me. In HR interview held just only for 5 Min and
it’s a really a silly interview.. I felt sleepy during this interview…after me
there two interview is going on…..
It
was 6:15.. still sun is not get up from bed.. some light ray is shown from the
east corner of the sky.. some bird maght wake up.. some people are returning from
home.. the sound of Bus. Auto and life world is just to wake up…we r the three
people are waiting for our luck…the HR came out from a room .. in her hand
there is a paper.. may be some name was written on it.. is my name would be appeared
in that list?
She
declare that they are very glad by taking interview from my clg.. And they
select final 3 student from my college..now the game is over .. I m out of
placement..they welcome us .. handshaking .. and finally give some gift to us..
and told us they will send offer letter via mail…
It’s time to return to room… and I know It was 2
hours late from my daily sleeping time…..
