Went to Bombay a day before. Stayed in IIT Bombay because I had few facebook friends. To my luck , even they had BARC Interview. We all went there. There was initially a check up of all the certificates and to and from tickets for travel allowance. The interview went on like this
1. Graph of Voltage across capacitor vrs time with different values of R,L,C in series RLC Circuit.
2. Super Diode
3. A lot of confusing questions on whether some Mosfet is depletion or enhancement type.
4. Set up and Hold up time
5. Signals and Systems questions were mostly on finding the Fourier series and transform based on symmetry.
6. Some quality Control System questions.
With this.. My tour of India completed.
Starting from Bangalore to Madras to Delhi to Bombay.....................
Before putting some thing else, I want to summarize as to what all offers I had in my hand
1. IIT Bombay - Communications ( 1st round) and Electronics Systems ( 4th round)
2. IIT Madras - Communications ( 1st round)
3. IIT Delhi - IEC, VDTT
4. IIT Kharagpur - Micro Electronics
5. IISC Bangalore - Communications and Networking
The below given experience is by my friend K. Bharadwaj. I needn't had to go to IIT Bombay RA. He have put his thoughts. He tasted the success in IIT Bombay RA and I have put his experience.
M.Tech (EE)IIT BOMBAY (RA) Experience
It is usually very difficult getting VLSI in old IIT's for
ranks above 200(my rank is 295 and score 803 in EC).For such people,IITB
provides a golden oppurtunity with M.Tech
as RA(Research Assistant).It's a 3 year course but is nowhere different
to two year M.tech as TA(Teaching Assistant).Curriculum,Coursework and
placements are all same except that RA has to spend one more year.As an RA,one
has to take less courses per semester(3 as against 5 for TA) but has to spend
20 hours of work per week as against 8
hours of work for TA.There are two kinds of Research assistants
1.Institue RA
-One has to work in labs like electronics lab,VLSI lab to
help undergraduate students in performing experiments.These are concerned with
day to day activities of lab including maintainence.Even System administrator
comes under this RA.
2.Project RA
-Professors have funded projects from various sources.As a
project RA,one has to assist these professors in project and in administrative
work also as told by respective guide.
Now,the difference between them is in chosing guide.Project
RA will be assigned a guide at selection and cannot be changed.He is expected
to do his thesis work in same area as project alloted while Institute RA has
the freedom of choosing guide.
Selection Process :
Cutoff is put in gate score and are called.This
year(2015),cutoff is
660(GEN),596(OBC),440(SC/ST).It means ranks upto 1200 can also be called in GEN
There will be a written test and Interview as part of
selection process.
Written Test:It
has objective type questions in which some may require answers in one or two
sentences.Time duration is 2 hours
Consisted of 3 sections
Section 1 consists of MATHS,APTITUDE,CONTROL
SYSTEMS,ELECTRICAL MACHINES (50 marks as far as
i remember)
Section 2 consists of LINUX Basics(commands,networking
),Communication,DSP questions(50 marks ..or may be 60.. i dont remember
exactly)
Section 3 consists of Analog ,digital and electronic devices
(50 marks)
There is no need to attempt all sections.Because it is not
expected for a core electrical guy to know communications and vice versa.It is
essential to score in the area for which you gave preference.Questions level
were easy-medium but time was the constraint.this year,paper was lengthy enough
that scoring 50 in whole paper is great.I guess my score would be around 45
Now shortlisting happens on following criteria
Institute RA- 50 % gate score ,50 % written test
Project RA-75 % gate score,25 % written test
Till last year 2:1 people were called for the interviews for
the number of positons available.But this time it was 3:1.This year number of
positions for institute RA are 36(5 were for only electrical)
and 21 for Project RA(5 were pure electrical projects).120
odd people were shortlisted for Institute RA whereas 63 for project RA(around
300 people gave written test).Your name can appear in both lists but will be
interviewed only once in which you have to indicate preferences.
This is atleast 2 day process in which first day will be
written test.Resullts will be in website by Night.Next day,we assembled at hall
and we were given forms for giving preferences in Institute RA(Electronics
lab,VLSI lab,System administrator,Communication lab).Projects(abstracts were
given to us) seperately for institute RA and Project RA.we were then addressed by HOD who surprised us with a
new proposal this year to check laboratory skills for people who preferred
electronics lab in 1st or 2nd choices.We were taken to
WEL lab and were given an experiment to perform.It was implementing 3 bit
counter using a 4 bit counter (not the
usual kind but its easy.just that idea has to strike)and connecting it to a DAC
circuit given in question and verifying with theoritical values.
INTERVIEW :There
were 16 panels and we are alloted based on our preferences in the form filled
earlier.Each panel had 2 members.If you are shortlisted for both institute as
well as project(and dual degree (mtech +phd )also had interviews in same
timings.You have to write same test as RA if u have applied and have been
invited for that also),the panel asks you preference .I preferred project RA as
i had interest in a proj 'chip design for Physiological monitoring(healthcare)'
and had previous experience with my mini project in same area.I was asked to
introduce myself and I told about my
education and projects I did as major and mini.They were interested and asked
me about the circuit i used for mini project which had biasing,filtering and
amplication.I was asked about the opamp used in my project and why was it
specifically used(it was noiseless).We basically had a discussion rather than
being interviewed.Then the professor asked me a basic RC filter question and
asked me to draw outputs on R and C for a square wave input.Then asked when it
would function as Integrator and differentiator and what happens if the case is
opposite(RC>>T,RC<<T).All this took around 30 mins .Only one prof
asked me all this.I got to know that other prof is asking about digital
questions if we mentioned digital as interest.They asked me what I was doing
for the last one year as i was already passout last year.Thats all.They said
they were done.So simple it seems na ;).It was the simplest interview of all
the ones i had.They were asking only basic questions.So if you have good gate
score and performed reasonable well in written test and interview you can get
seat easily.If you have less gate
score,dont worry but perform well in written test and interview.Results will be
annouced in a week or two.
