NTPC INTERVIEW EXPERIENCE 2016

NTPC INTERVIEW EXPERIENCE 2016

NTPC selection process experience. (The last PSU interview for me)
Branch: ECE
Place : NTPC PMI , Noida
Reporting time : 8.00 am

Initially, there was breakfast. After breakfast, document verification plus you needed to fill a form mentioning your particulars started.
After filling the form, they matched the documents with particulars you filled in the form. Document verification was fast and simultaneously, GD was being conducted.
GD: Before starting GD they asked everyone in the group to give their brief introduction.
G D topic: Coaching institutes are good or bad for teen-ager 's intelligence?
12 minutes were given to discuss on the topic
My interview questions:
They asked about my family background. Next they asked what have you studied. I replied: GATE topics.
Then one person asked me some simple questions on signal system like he gave a signal and asked if it is linear or not. Asked to plot sin(t^2) and how is graph is different from sint. Then he switched to transformer where he asked how does it work and on which principle. Then he gave a ckt of transformer with primary connected to sinusoidal AC and he asked to draw flux lines in transformer and current direction in secondary.
Other person in the panel started his questions on my work ex. He started with basic questions, then ultimately went into details after which i have to say sorry sir, I don't know.
Other person said that your interview is over.
Then I went out of the interview room with mixed feelings about the interview.
Interview duration : 30 mins.
Hope this helps for future aspirants.
Thank you Saurav.

Microwave Devices and Circuits [For IES,PSUs and University Exams]

The major prerequisites for right away studying microwave devices and circuits are :

1.Basic knowledge of Electromagnetic Theory
2.Network Theoy (S parameters)


Microwave subject at UG level mainly deals with following topics:

1.Microwave Transmission Lines (basics)

2.Cavity Resonators
Rectangular and circular waveguide resonators.

3.Klystrons
Reentrant cavities,Velocity modulation,Bunching,Reflex klystron.

4.Travelling wave tubes 
Slow wave structures,Helix TWT,

5.Magnetrons
Magnetron oscillators (PI mode,Strapping,Mode jumping)

6.Solid state microwave devices
Microwave BJTs,Tunnel Diodes,Gunn Diodes,MESFETs and PIN diodes.

7.Microwave Hybrid Circuits
Magic Tee,Hybrid ring,Directional couplers,Circulators,Isolators.

8.Microwave Measurements

ANALOG CIRCUITS

ANALOG CIRCUITS

   This is a subject where you can score easily once you grasp the basics properly (12-14 marks).You don't even need to invest too much time for revising this subject once you are clear with the fundamentals.

 Sedra and Smith’s "Microelectronic Circuits" is an all-inclusive book, which serves to detail out the ABC of  Analog Circuits in a detailed manner. The concepts are clearly explained and easily understandable. This book along with "Design with Operational amplifiers and Analog integrated circuits" by Sergio Franco Covers almost every topic in analog circuits for GATE ECE.

Lecture Videos

Now  that i have uploaded many text materials,let me share with you some interesting video lectures i have come across during preparation.

1.Microelectronics by Behzad Razavi 

One of the best lecture series to start studying the basic analog circuits at UG level.I highly recommend this for Semester 3 students of Electronics branch.


2.Signals and Systems by Oppenheim



This is vintage stuff,Alan Oppenheim is the man to go for if you want to learn signals and systems from scratch.The lecture series is quite old,but doesnt lack the clarity of content.I would also recommend students to solve problems from his text here.


3. Network Analysis and Synthesis by Dutta Roy (NPTEL)


Dutta Roy lectures stand out among other NPTEL videos because of his dedication and clarity in explaining topics with lucid examples in multiple domains be it network theory,signals and systems or digital signal processing.


4. Control Systems by Brian Douglas



This one is an illustrative and short videos on various topics in control systems recommended by one of my friends.There is also another NPTEL lecture series by Prof.Madan Gopal available here which is also very good.


4.Solid State Devices  by S.Karmalkar 



The language and content of this lecture series is very good.I feel this is one of the best lectures for preparing well on Electronic Devices topic in GATE.


5. Analog Signal Processing by K.R.K Rao




K Radakrishnan Rao is regarded as the ANALOG GOD who has taught for over 20 years at IIT-M and is currently working as Distinguished Member and Technical Staff (DMTS) (Analog Training) at Texas Instruments, India.These lectures are a must watch for those who are interested in pursuing a career in VLSI.


6. Digital Circuits and Systems by S.Srinivasan






This NPTEL lecture covers all essential topics of Digital Electronics course and i would recommend students to read Digital Design by Morris Mano in parallel while watching this lecture series.


UPDATE: Check out the NPTEL Lectures complete list for GATE ECE Preparation here.
