Technical Questions in the second round –

—————————————

[1] What are the current trends and areas of focus in IT.

My Ans. Talked about emerging trends of S/W Engg and ISO 9000 stuff

(gave vague ideas about them as I don’t know much nor do I care

about these topics myself ;-)). Then mentioned the proliferation of O-O

methodologies and their usefulness in speeding up development process,

code re-usability, ease of maintenance, ease of bug-fixing.

Thirdly, mentioned the work going on in High-Speed N/w - FDDI, ATM,

Fast-Ethernet(100Mbps). Told whatever little I knew about ATM in

response to another question.

[2] What is a Micro-Kernel architecture.

My Ans. This is a developing area in OSs where instead of building the

kernel as a single monolithic structure starting from scratch, it is

built as a set of layers. The micro-kernel provides only the bare-bones

like Device-drivers, rudimentary filesystem support etc. on which,

depending on the intended area of application of the OS, it can be

customized to provide various higher level OS features like

Multiprocessing, IPC, etc.

} /* End of for() */

a) Describe the memory management policies in Unix. How is paging

implemented? How page faults are handled?

Seems to be a favorite question for these chaps —- Maurice Bach.

b) Write a macro in C for swapping two nibbles in a byte.

-Use the shift operators and be careful while defining temporary

variables( if you do so) as you have to write a macro. Otherwise

it is pretty simple.

c) What is the CPU-scheduling policy in Unix? - Round robin scheduling

with multilevel queues.

d) Diffrence between short term, long term and medium term scheduler.

-First two should be peaceful. The last one is also known as

swapper. (See Taenenbaum and/or Peterson)

e) Name various page-replacement policies. Which can be implemented

both with and without pre-emption? - see Peterson.

f) Describe the Sliding window protocol. What is it’s advantage

over stop-and-wait? - Saves bandwidth. (Taenenbaum please)

2ND INTERVIEW (Both personal and technical interleaved)

a) Tell us something about yourself.

b) Aren’t you going for higher studies abroad? Why?

c) Rank and CGPA. MSites do not have ranks but still they wanted to

know my approx position in my batch.

- Shady question. It is your job to convince them that for

MS, grades do not hold any meaning.

d) What is re-entrant code? — Non-self modifying code. Can be

shared by many processes simultaneously. Gave e.g. of text-editors

like ‘vi’.

Counter Q: But then no code modifies itself. What does ‘non-self

modifying’ mean? —- I don’t know for sure.

e) Diff between compilers and interpreters. Some fundaes about

how to link code in different files.

f) What would your friends tell us about you if we ask them?

Standard question for everyone.

Second interview: (fully personal) — This was more interesting;-)

a) What did you feel about the ppt? — wasn’t very impressive

so gave some shady answer.

b) Have you heard of creativity? — Ya.

Have you heard of Bernard Shaw? — Ya.

(Then he rattled off some quote of BS regarding creativity)

What do you say? — I put some shadiest fundaes regarding

visionaries and Leonardo da Vinci conceptualising Helicopters

in his time!

———–

i) Tell us something about yourself. (This has to be there)

iv) Can you describe your project in short?

v) Why did you take 2-1/2 years to complete (My case!)

vi) If given the job when can you join. (Caution: Don’t think that if

you give some unreal early deadlines they will offer you the job.

Always play safe and give a deadline by which time you are sure to

complete and join. Asking for extensions is the worst scenario).

Tips: Be confident, frank (But need not give away information which may weigh

against your case), free (use first names while addresing them, so be

alert when they introduce themselves) and cheerful (attend an interview

with a positive frame of mind). Remember you are IITians and you always

have an edge. That may sound arrogant, but its true.
