what is an electronic engineer expected to know if he is inducted as a fresher ?

Answer 1

These are some of concepts I expect of new hires during their technical interview.

1. How voltage dividers work
2. Pi and Tee networks and their applications.
2. Simple OpAmp circuits (inverting, non-inverting, follower amps). Calculating gain, explaining how they work.
3. Filters, RC, 2-pole, 3-pole, what a cutoff frequency is and how you might derive it. Filter shapes (butterworth, bessel, elliptical, etc.) and why one type might be used vs. another.
4. Simple diode circuits -- clamps, zener regulator -- simple explanations of how they work.
5. Logic circuits -- simple truth tables for AND, OR, etc.
6. Logic circuits -- counter. Explain the operation of a counter
7. Logic -- glitches and how to get rid of them (through use of synchronous circuits).

Those are a few of the basics.

For the more advanced candidate:
1. Name as many parameters as you can that cause an ideal OpAmp to be non-ideal (I can name 22 off the top-of-my-head, as of last try).
2. Draw the state diagram for a change-of-state detector or other equally simple logic construct.
3. Sampling Theorem and anti-aliasing filter design -- explain what you know.
4. Signal integrity on printed circuit boards -- how do you prevent ringing and undershoot on high-speed pcb traces?

Answer 2

I think talent, intelligence, work ethic, and problem solving ability are more important than any specific knowledge an entry level engineer has gained from his/her studies. So you didn't take a microprocessor class in college. If you have the talent to pick up a CPU user's manual and figure out how to create a proper design from it, I don't care if you didn't study it in school. The field is too broad to cover every topic in college. In my opinion college is where you learn fundamental concepts and problem solving ability. The nuts and bolts of the job will come later.

Answer 3

ur expected to know the basics.most of the companies will be working on technology which will be probably much advanced than that u have studied in college..Your degree will give u the base knowledge.Blundering on some thing like ohms law is defenitely a no no...dont be nervous . admit if u dont know some thing and learn fast....
