,1. Tell me about yourself?
It seems like an easy interview question. It's open ended: ”I can talk about
whatever I want from the birth canal forward. Right?”
Wrong. What the hiring manager really wants is a quick, two- to three-
minute snapshot of who you are and why you're the best candidate for this
position.
So as you answer this question, talk about what
you've done to prepare yourself to be the very
best candidate for the position. Use an example
or two to back it up. Then ask if they would like
more details. If they do, keep giving them
example after example of your background and
experience. Always point back to an example
when you have the opportunity.
"Tell me about yourself" does not mean tell
me everything. Just tell me what makes you
the best and fit the job requirements

,2. What is a differential amplifier? Also, explain CMRR.
Differential Amplifier: The amplifier, which
is used to amplify the voltage difference
between two input-lines neither of which is
grounded, is called differential amplifier.
This reduces the amount of noise injected
into the amplifier, because any noise
appearing simultaneously on both the input-
terminals as the amplifying circuitry rejects
it being a common mode signal.
CMRR: It can be defined as the ratio of
differential voltage-gain to common made
voltage gain. If a differential amplifier is
perfect, CMRR would be infinite because
in that case common mode voltage gain
would be zero.

, 3. Where do you see yourself in five years’ time?
What the interviewer really wants is to see that
you’ve thought about your future, and gauge your
ambition. They also want to verify that this isn’t just
a stop gap position.
Although all of your answers should be tailored to
the organization and position you’ve applied for, this
is especially the case with this question. If you’re
going for an entry level position, for example,
explain how you’d like your career to progress (e.g. ‘I’d like to progress to a
Senior Software Engineer’ or ‘I see myself being a team leader…’).
If you’re going for a more senior position, explain how you’d be looking to
move the company forward. Have a look at their business strategy or corporate
objectives before the interview, and explain how you can help in achieving
them.
