I applied through college or university. The process took 1 day. I interviewed at e-con Systems (Sivakasi) in Jul 2019
Interview
Overall interview process was good. Most of the questions were asked from basic electronics because I cleared hardware round. In generally they were conducting two different test 1.puzzles
2.hardware questions
Interview questions [1]
Question 1
Technical round
1.tell about your self
2.what is voltage and current? They were expecting exact definition with real time example
3.what is resistor why we use that
4.property of inductor and capacitor
5.tell about your project(it should be in detail)
6.what is rectifier
7.draw and explain full wave rectifier
8.how to reduce the ripple content in full wave rectifier.
(7 and 8th question should be explained through diagram and waveform)
9.audio amplifier power is 12w when connecting 12ohms loud speaker. Now I replace the 4ohm loudspeaker instead of 12ohm now what will be the power of audio amplifier.
10.some of circuit solving questions are there I will send later.
11.what Is D flipflop and write a truth table along with draw internal logic gate diagram.
12. Is capacitor allows dc if yes why.
13. Take 1k resistor and 0.1uf capacitor are connected in series and it is connected to 5v source now how much time required for capcitor gets fully charged. Note:capacitor voltage is
also 5v
14.when 5v battery is connected to 12v capacitor how much amount of voltage is stored in the capacitor. Whether it is 5v or 12v. With reason.
15.what Is diode
16.tell types of diode
17.differnce between normal diode and zener diode
18.draw any dc circuit diagram with inductor and give explanation.
19.capacitor charging curve is exponential or linear. With reason
20.you should explain the question were asked in first round and 2 round.
I appeared for hardware role. For both hardware and software, there will be 3 rounds, the first will be an technical round covering all fundamentals from ECE. 2nd round will be HR and the 3rd with the director. You will be tested on your core knowledge on all the rounds.
Interview questions [1]
Question 1
Circuit Diagram of projects mentioned in resume.
Draw all the symbols of basic electronic components
The interview process may range around 5 to 7 rounds. Aptitude, Technical, F2F interview. They expect you to have deep understanding on the projects that you have done. The first round usually consists of aptitude and puzzles.
First round is written which contains aptitude, logical thinking,Basics of electronics and circuitdand some programming in C questions
Second round is the technical interview.
Final round is the HR or manager interview.
