WHat is software life cycle ?

How much time is spent usually in each phases & why ?

Which one do U want to work if selected in Honeywell ?

( I said I don’t like testing )

They asked why ?

I said it is a boring job. Then they tried to analyse

the knowledge in testing.

What is testing ?

Which are the different types of testing ?

Then they explained the way they do testing. They said that they are doing testing in requirement phase & design phase so that if any problem comes in those phases it is not ncecessary to go back & change the requirement or design. All the test processing is automated.

Why do U want to join Honeywell technologies?
Ans : To get a practical feeling of Real-time systems.

Do U know C++ ?

How good are U in C & C++ ?

Rate U’rslef in both C & C++. ( 1 – 10 marks)

 

Second round of placement paper (around 45 minutes )

They wanted a bio-data at the time of inteview. I gave the placement office bio-data & in that one there was column ‘Major subjects studied’. Many of the questions came from those.

Explain U’r research work.

Lot of questions from it.

What is a distributed system ?

Some questions about CSP. ( I kept quiet)

Which languages do U know ?

What are the differences between Pascal & C.

I said Pascal is a strongly typed language.

Then what is typing & its advantages ?

Then he asked some questions from Compiler construction & Lisp.

WHich are the different computer architectures ?

What is the requirement in MIMD ?

What is the difference between RISC & CISC processors ?

Difference between loosely coupled & tightly coupled systems ?

What is an open system ?

Still a lot of questions from software engineering .

Which are the different phases in Software life cycle (asked again)

Why is analysis & testing phases very important ?

Which methodologies are U familiar with ?

Have U worked in windows ? (Yes)

What is the difference U have seen from a Dos environment ?

I said it event driven .

So what do U mean by event driven ?

How do WinMain look like ?

How the messages are processed in Windows ?

 

(Queue of events)

What are parameters needed to distinguish an event ?

Have U done any network programming ?

Why networks are layered ?

What is the advantage of that ?

How many layers are there in OSI ?

WHy is it called OSI model ?

Are U familiar with network topologies ?

Which are the different network toplogies ?

Tell an example of bus type network.

I said ethernet.

What is the Bandwidth of ethernet ?

Explain the advantage & disadvantage of ethernet ?

Which is the protocol used in ethernet. (CSMA/CD)

Why is it called so ?

If all stations tries to communicate at same time, what will happen.

What is binary exponential backoff algo ?

What is the advantage of Ring network ?

Compare it with ethernet.

In a real-time system which one do U prefer & why ?

What is the basic requirement of a real-time network ?

Which one is costly – ethernet of ring networks ?

Some questions form OOSD & Digital signal processing.

What is inheritance, encapsulation etc.

Third honeywell test Round (15 minutes)

Asked about the percentages & marks during SSC, PDC, B.Tech & MS.

When can U join ?

Who is U’r guide ?

How do U perform in the first two interviews ?

WHy have U given Honeywell as dream job ?

Some more personal questions Fourth Round of honeywell test(45 minutes)

 

1. Aptitute test questions : 15 Minutes, 20 Questions

Towards the middle questions are easy than from the front.

eg. Product of three consecutive nos. 210. What is the sum of two least numbers?

ans.: 5 * 6 * 7 = 210 , sum = 11 is answer

 

eg. If the area of the sqaure is increased by 69 % how much the length of the side will increase?

ans.: 13 (i think)

eg. if the sum of five consecutive nos. 35? how many prime nos

are there :
ans: 5 + 6 + 7 + 8 + 9 = 35 so two primes

eg. if the length of the rectangle is reduced by 20% & breath is increased by 20 % what is the net change ?

ans.: 4 % decrease

HONEYWELL PATTERN – APR 2005

HONEYWELL PATTERN – APR 2005
HI ,

this is the pattern i have..i didn’t attend for honewell so don’t expect any more than this plz do check this and don’t send any queries to this id no use.

Their pattern is
OS : 10 Questions
C : 10 Questions
C++ : 10 Questions
Java : 10 Questions

OS is compulsory and you can choose any one of these three language. I had
chosen C++.
Here is few question I still remember. please do not go on my answers they
may be incorrect also.

C++ Questions
1) If there is one class template which has one static member variable that static variable will belong to
a) Every instance of class template will share the same copy of static variable
b) Every instance of class template will have its own copy of static variable.
c) Compilation error
d) Don’t remember.

2) What is template specialization ???
a) define a new template class for a specific data type.
b)c)d)

3) How we will overload operator *+= such that
obj1 *+= obj2;
implies that
obj1=obj1*(obj1+obj2);
four choice were there last option was d) it is not possible I checked
that option.

4) IN C++ what does the operator overloading means.
a) Giving new meaning to existing C++ operators
b) defining functionality of existing C++ operator for user define objects.
c) defining new operators.
d) don’t remember.

5) what is ‘>>’ in C++
a) right shift operator and insertion operator depend upon the use
b) right shift operator and extraction operator depend upon the context use
c) right shift operator and insertion/extraction operator depend upon the use

6) class A
{
int a ,b;
A() : a(0)
{b=0;}
};
if you create obj of this class as A obj;
a) b will be initialized before a
b) a will be initialized before b
c) both will be initialized together
d) none of these.

OS Question
All OS questions were based on basics of UNIX all small -2 commands.

1) how image of one process can be replaced by other process
a) exec
2) how image of one process can be copied to new born process
a) fork
3) how can you list all the files used by a particular process
4) how do u create a link of file

C Questions

I did not attempted the C paper but still I just had a look on C and java
paper. in C most of the question were programs and their out was asked in LINUX environment.
1)
int main()
{
char *a= “Novell”;
char *b;
b=malloc(10*sizeof(char));
memset(b,0,10);
while(*b++=*a++);
printf(“%s”,b);
return 0;
}

2) int main()
{
printf(“Hello”);
fork();
printf(“World”);
}
