These are the rounds VVDN Tech conducted for
us.
Round-1:
First round is written
test, it is not objective but descriptive. The written has three sections
-> Aptitude
-> General
Electronics(Digital and Analog).
-> C
Aptitude- They asked
some problems based on Train(Speed and Distance),Time and some apti questions.
General Electronics-I
remember only few questions they gave some digital design's and they asked the
truth table for them.
C- basic C questions.
Round-2:
Two people Interviewed
me in this round.
The Second round is Technical round. First
they asked me some simple C questions(basic) and later Linux basics. Then they
moved to basic electronics.
They asked me to calculate Relative resistance
for the given Network(both open and short circuits and asked me relative resistance).
Then they moved to Micro-Controllers and asked
me some basics mainly on the board and controller of our project done.
They also concentrated on Communication skills
and attitude.
Round-3:
This is the final technical round and there
will be no HR-round.
In this round One guy interviewed me. He first
asked me on my B.Tech and Vector projects.
Then he asked me to write C programs using bit
wise operators
I remember one question, he asked me to write
a*b operation without using '*' operator using single for loop and bit-wise
operatiors.(not simply adding a b times).
Then he moved to
Digital Electronics he asked me to design Digital Circuit for the given truth
table, he gave one criteria where I have to design two port n/w where if you
alter the i/p ports either port1 and port2 '+' and '-' or port1 '-'
and port2 '+' you have to maintain const o/p only port3 '+' and port4'-'.(where
port1 and port 2 are i/p ports and port3 and port4 o/p ports).
All the best guys.
