Model Interview Pattern
1. In radar we may know
how a CW radar works and what are its applications. That?s not enough! You
should know why the CW can be used in those applications and what types of
radar can be used in those applications other than CW radar.
2. In digital we know how to reduce a Boolean expression using K-map. But do
you know difference between looping 1s and 0s in K-map? Do you know there is a
limitation in Kmap? Do you know any other method to reduce the expressions? Is
there any limitation for that?
3. In mechanical we have heard a lot about 100cc or 150 cc bikes. What
actually cc here means? Is there any relationship with that with performance
if so how and why?
there any 100% efficient Carnot cycle? Why?
4. In electrical we have heard a lot about transmission loss why it is caused?
Can we prevent it ?
5. In Computer you know methods of sorting? Which is the most efficient and
6. In Physics do you know what is the cause of hall effect?
have a first hand experience of an ISRO interview.
(Ahmedabad) panel comprised of 6 members, very senior scientists. They asked
about B.E project, subject questions were picked up from the B.E project. Like
if your project is on Commn, they asked questions from Commn.
At NIT, Trichy ISRO dropped in for campus recruitment, panel members were from
ISRO Trivandrum and ISRO Bangalore with some 20 years of experience in ISRO.
people on the whole were in the panel. 1 was an expert in microwaves another
person in DSP, Digital Commn, VLSI, third person was chairman, I believe
first made the usual formalities like doc verification and the usual questions
like Did u appear for GATE? How did u come 2 NIT, Trichy for PG (GATE / NON
GATE)?? What was your rank in the entrance test conducted by NITT to get in
they asked abt my M.E project. Here at NITT, we have phase-1 project and
phase-2 project at 3rd and 4th semester course.
i told that I am working with IP over WDM networks. They asked me from WDM
technology, to compare microwave and fiber optics, guided and unguided commn
differences? WDM components, about IPv6.
member asked me from microwaves. Some questions raised by him
Eqvt ckt of transmission line and explain all the primary and secondary
losses associated with transmission line
gain, isotropic antenna?, antenna applns at different freq
sources - klystron, magnetron etc.
member asked me from digital commn
Sampling theorem, aliasing effects, digital modulation (compare BPSK and
BFSK), what is FFSK?, line coding (compare Manchester and NRZ scheme), turbo
codes??, trellis coded modulation??, advantage of cyclic codes
questions from spread spectrum also - like how anti jamming is achieved??
only basic fundas here also. Confidence is the key and it's better to have a
firm grasp on the subjects related to project.
the panel members were old people, questions from microwaves, antennas, trans
lines are sure to come forth.
fact questions from microwave engineering, antennas and transmission lines
were asked for all people
