BARC INTERVIEW EXPERIENCE(MECHANICAL)AIR-244

The panel consisted of 4 members. 

They began with a brief 10-15 minutes discussion about my homeplace and reasons why I left my previous job and also asked what I know about BARC Interviews.

They were very friendly and easy going and told me to be calm and stress free.

After that they asked me to write down my favourite subjects.

I wrote:

1)SOM 

2) Thermodynamics 

3) Heat Transfer 

4) Fluid Mechanics

Q-1: A container containing 10 kg of water is kept on weighing scale .If a string is tied to a 1 kg ball (density 10 times than water) and is immersed in the container, how the reading of weighing scale will change?? (from the time when ball is completely outside the water to the point when it is completely submerged; assuming tank is sufficiently large so that water does not overflows out of tank).

Q-2 A gas is contained in a frictionless cylinder-piston arrangement whose walls are sufficiently long and the surface above piston is exposed to atmospheric pressure. The whole assembly is turned upside down suddenly (so that pistons starts moving down due to its weight). They asked me to draw P-V diagram of the whole process till a steady state is reached.

Q-3.A balloon is being inflated with air isothermally so that both pressure and volume of air inside balloon is increasing. Then why PV=RT is not followed in this case?? (LHS is increasing while RHS remains same)They also asked me one more question on fluid which they linked with the design afterwards (although I didn’t wrote design in my favourite subjects).

They kept on providing hints in the whole interview which lasted for one hour.

IOCL INTERVIEW EXPERIENCE

IOCL Interview Experience of selected students based on GATE 2017 score.

I was interviewed at IOCL's IIPM (IndianOil Institute of Petroleum Management) Gurgaon on 19th June, 2017.

GD Choices-
1. The state of Indian Engineering Education scene due to opening of way too many colleges.
2. Should 0% Interest loans be provided to Farmers in today's times of farmer unrest.

GT (Group Task) - 

Only two IITs have made it to the Top 200 rankings of World's Best Institutes. As directors of various IITs, find a solution to make sure that not just two but many more IITs could crack the Top 100 rankings.

The GD/GT Panel seemed uninterested, hardly even looking at which candidate is even speaking at GD. Payed a little more attention during GT to notice if we were interacting or not.

Interview- 

Panel consisted of Five Members-
1. Tell me about yourself.
According to my answer from there-
2. What you did after job ?
3. Would it not have been possible to do along with job ?
4. Best achievement while being at job ?
5. Describe in detail the CSR activity you mentioned.
( because of my job at Automobile Company ).
6. BS-3, BS-4, BS-6 Changes in fuel and changes in vehicles design.
7. Is Indian automobile market ready for them?
8. Crankshaft Material and manufacturing and why exactly?
9. CRDI and it's effect for a common man.
10. Welding Vs Brazing.
11. Bearings in IC engine.
12. Give brief description about IOCL major businesses.
13. Do you know how many refineries we have?
14. What is our petrochemical brand name and it's products?

The panel was very senior and yet very very humble and friendly.
They listened to each and every answer with at most attention, allowed me to answer with however much time I needed and placed counter questions only after I had finished my part.

After answering over dozen of questions over half an hour, the most senior of them, asked if anyone wants to ask any more (in a comic way) and we all laughed.

Finally, HR mam asked last question-
15. Which was the gas responsible for Bhopal Gas Tragedy and the company name? (because of my college was in Bhopal).

With the final answer, I was allowed to leave.

IOCL Interview Feedback

Interview happened at IIPM Gurgaon.

GD- Should death plenty be banned or not ?

GT- U have to promote Pradhan Mantri Ujvala Yojna in remote areas of our country and for this list the problems you may face during this project and u will rectify them.

Interview- 4 members total.

1. Tell me about yourself which is not written in these forms in front of me.
2. What is coefficient of restitution.
3. What is Black hole ?
4. What is black body ?
5. What is differential and what is its purpose. Do we have 2 differential in 4 wheel drive.
6. What is blanking ?
7. What is the efficiency of a thread? what is the efficiency of screw jack?
8. What is coupling and what it is used for and list some of its examples.
9. What is camber
10. Let you are shift in-charge at your shop floor and some contractor worker slapped on permanent worker and due to this all the permanent workers went outside the factory and decided not to work. What you will do in this situation?

By reading all this you might think that I told them automobile or physics is my area of interest but trust me neither I had written in my CV nor I told them regarding this.I don't know why they were so much focused on automobile.

Actually they have a set of questions written on a page and they will ask you from those papers only unless you have some work experience.
So prepare your mind as they can ask you anything,even out of your domain.

Anyways best of luck !!

WHICH TEST SERIES TO JOIN..??

Also my friends allowed me use their few tests of Ace Academy and Exergic test series.

How many test series to join?

          Joining one good test series and attempting it proper planning is enough to practice and analyse your preparation. Managing two test series is quite a cumbersome task as you have arrange your preparation schedule according to tests schedule of both test series but eventually it will be help you if completed diligently. Here's the link to get an idea about the level of Made Easy, Ace Academy and GateForum test series questions..

https://gateflow.blogspot.in/2018/05/gate-test-series.html

In case of any doubt, do comment.

And share it among your friends as they will also get benefited.  

HOW TO PREPARE

GATE exam questions aren't like  typical subjective questions of  your college exams instead they are objective type and application oriented.

Before you start any subject for e.g. Strength of Material (SOM) first go through its GATE syllabus and then have a glace at the previous year Gate questions asked from this subject.
Try to solve some questions and check how much hold you have on your concepts and ascertain your level. Never try to mug up any topic instead learn the concept behind it which is very essential for problem solving approach.

For concept building refer standard books of good authors and don't rely on local authors book that you had referred during your college days.
You can also refer Hand written notes of MADE EASY Classes as it contains all the necessary content as per GATE syllabus.
Give your 1st preference to Standard Reference books if you have got ample time for your preparation (especially 2nd Year Students).
Now , once you're done with all the concepts of SOM again try solving previous year GATE questions on it. 
Try to solve more than 70% previous year questions accurately as it will increase your self confidence and practice more questions to improve your accuracy.
I am attaching here the link of Test Series from where you can practice more Gate oriented questions to improve your accuracy.
Here's the link to download Test Series question

https://gateflow.blogspot.in/2018/05/gate-test-series.html

If you're not able to solve sums then analyse where you went wrong,identify the type of mistakes you are doing whether it is a conceptual mistake or a silly mistake and try to rectify it and always read questions properly and take your time to understand it.
In this way you can master one subject and repeat the same procedure for another subjects too.

Here's the list of standard reference book and study material that one should follow:
TOM : S.S.Rattan
SOM : B.C.Punamia, Sadhu Singh
Engineering Mechanics : A.K.Tayal, Timoshenko
Heat transfer : P.K.Nag, J.P.Holman, R.C.Sachdeva
Thermodynamics : P.K.Nag (solve all solved examples and read theory)
Fluid Mechanics : R.K.Bansal, S.K.Som
Industrial Engineering : Made Easy Handwritten Notes, Hira Gupta
Production : Kalpakijan, Amitabh Ghosh and Malik
Material Science : Kodgire, William Callister
Machine Design : V.B.Bhandari
Mathematics : B.S.Grewal, Erwin Kreyszig
RAC : P.K.Nag,Made Easy Handwritten Notes

Also refer Hand written notes of Made Easy for shortcut tricks and tips 

Remember guys ,GATE exam is all about concept building and accuracy.
