HONEYWELL
Here is the questions that was asked to one of my ms friends in
last years campus interview (Honeywell).
This was not included in the database in ~mrb.
/***************************************************************/
Hi MRB,
I am out of placement after getting selection in Honeywell,
which was my dream job.
Honeywell conducted a test in IIT and Interview was in their
office at B'lore.
Test contained 100 multiple choice questions divided into
a) Verbal ability (15 ques)
b) Numerical aptitude (15 )
c) Logical and analytical ability (15)
d) Elementary computer science (10)
d) Programming langauages (20)
e) Operatins systems and Data structures (25)
Not sure about the number of questions.
Verbal ability questions contained 3 parts.
a) One passage is given and U have to answer 5 questions
b) Some words are given and their synonyms have to be written
c)
Numerical aptitude and Logical questions were the usual stuff.
---------------------------------------------------------------
I had 4 rounds of interview.
First round (around 45 minutes) contained, questions from Real-time
-----------
Systems (my research area), operating systems and Software Engineering
Explain U'r research work.
What is a Real-Time System ?
What is the difference between Hard and Soft real-time systems ?
What is a mission critical system ?
What is the important aspect of a real-time system ?
Explain the difference between microkernel and macro kernel.
Give an example of microkernel.
Why paging is used ?
Which is the best page replacement algo and Why ?
WHat is software life cycle ?
How much time is spent usually in each phases and 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 and design phase so that if any
problem comes in those phases it is not ncecessary to go back and change
the requirement or design. All the test processing is automated.
Why do U want to join Honeywell ?
Ans : To get a practical feeling of Real-time systems.
Do U know C++ ?
How good are U in C and C++ ?
Rate U'rslef in both C and C++. ( 1 - 10 marks)
Second round (around 45 minutes )
------------
They wanted a bio-data at the time of inteview. I gave the placement
office bio-data and 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 and C.
I said Pascal is a strongly typed language.
Then what is typing and its advantages ?
Then he asked some questions from Compiler construction and Lisp.
WHich are the different computer architectures ?
What is the requirement in MIMD ?

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
