A REAL EXPERIENCE ABOUT BARC INTERVIEW (MECHANICAL ENGINEERING )

2013-04-01T07:46:00.000-07:00

Sorry for grammatical errors and mistakes as I was just
concerned with the content and didn't had sufficient time.
 
      I am a student of IIITDM Jabalpur, from Department of
Mechanical Engineering. I qualified the written exam
conducted by BARC and attended the interview.
First let me tell you that this is the most genuine and
toughest interview among all the PSUs. This is the best
interview methodology that they adopt.
They just ask for very basic questions of Intermediate
(12th) level and want to check the basic understanding.
Almost all the questions are practical questions no direct
relation with the knowledge of core technical. In this way
they look for the way you approach to solve a problem.
Because the post they offer you is scientific officers’
post. This is a research oriented job that requires the
great skills and knowledge to solve a real practical
problem. So, this was a basic idea about the interview. Now
let's talk about the methodology, actually they ask you 4-5
subjects in which
you are more comfortable and ask the basic questions. But
keep in mind that you are really comfortable with those
subjects and you should be thoroughly prepared. Because they
will try to divert you from your answer and will drill on
topic till you surrender. But anyway you don't worry
even if you are not able to solve a problem for whole but
the way you approach and the basic concepts should be
correct. They are generally the minimum time
for interview is more than 45 minutes. Even the person they
know will not be qualified; they drill him at least for 45
minutes. As the interview timing cross more than 45-60
minutes, your chance goes on increasing to get selected.
Finally If they are satisfied with your performance then
they give you a medical slip that insures your eligibility
fir the interview. Final Result depends on the no. of posts
and the merit list prepared on the basis of marks you
achieved in written and interview. I wish you all the best
for your interview.

It is well known that hard work and the luck both are that
major factor that plays important roles in every exam. Your
Luck also plays an important role that by which panel you
are going to be interviewed. During my interview I was a
victim of bad luck so I could not qualified the interview.
I had heard that the panel members being very helpful they
bring you out of the pressure if you feel during the
interview but this was not true in my case.

Anyways, I entered in the room, there were 5 members. The
committee chairman asked me about my hometown. The whole
conversation was in Hindi, so the people who are from Hindi
background they don't need to be afraid of this problem in
PSU interviews.
Then he asked me "Is it your first interview or you 
have gone through any other interview?", Me: "Sir this is my
first interview". This normal conversation is just to make
you feel good and to make 
you comfortable.
Chairman: So you have done your B.Tech from IIIT?
Me: Yes Sir.
Suddenly another person interrupted as he was looking at my
cv, he told to the chairman that I got first Prize in solid
modeling Contest. This was a curse for me for that interview.
Chairman: So you got first prize in Modeling?
Me: Yes sir.
Chairman: What is Computer Aided Design?
Me: I told.
Chairman: You have been taught the Finite Element Methods
course?
Me: Yes sir.
Chairman: Can you do the analysis of a cylindrical pressure
vessel?
Me: No sir, actually we just learnt the analysis of one
dimensional objects.
Chairman: But you know the basics of analysis steps?
Me: Yes sir.
Chairman: What will be the first step?
Me: We will take the symmetry and will not require going
through the analysis of whole section.
Chairman: Draw the element of symmetry?
Me: I drawn.
Chairman: Next step?
Me: Boundary conditions and Forces.
Chairman: What will be the boundary conditions, forces etc.....?
I could not give the answers, and the trials were wrong and
I was totally confused. but he rammed me a lot and wasted
almost 10 minutes.
It was a bad impression that lead me through the darkness.
Then he asked me to put the name of subjects I studied in
B.Tech as our curriculum is different from other colleges
curriculum, It has major emphasize on Design. So under
pressure I was not able to recall the subjects. I started to
recall them and listed on the paper but didn't minded to put
them in the order
I prepared. Actually I prepared Material science,
Thermodynamics, Heat Transfer and Micro Metal Forming (for
the fabrication of MEMS devices, a recent topic). So they
just started asking the questions randomly from the subjects
they got in that list. After a sometime chairman asked me
about the subjects I am comfortable. I told and given the
preference to Micro-Metal Forming that was a new topic for
him and he decided to get out of the topic and asked about
the issues when we go through the micro forming. I told that
as we go from macro size to micro, the strength, isotropic
behavior and surface roughness changes and affect a lot.
Then he asked how surface roughness comes into picture?
 Me: As material thickness approaches towards micro size,
the no. of grain boundaries becomes fewer and grain
boundaries sizes are in the order of microns so the very
early surface has a lot of deviations that comes in picture.
Then he asked: What is inside the space between two grain
boundaries; Gas or Vacuum? 
Me: Sir Vacuum. He Said: You are wrong, go and refer the
books. and in this way he came out of the topic that he was
trying for.
So, I will suggest you not to give any new topic as the
persons taking interview may or may not be comfortable with
that and it may be a curse to you.
In Thermo….. he asked
He: there is a cylinder-piston system that contains a gas, a
weight W is kept on piston what will be the pressure?
Me: Sir W/(g*A)---A: area, g: gravity (It was wrong actually
I was in such a pressure that to calculate the pressure I
was using the formula M/A)
Then another person asked me about "g", why I am using it ?
I confidently said: sir to get the mass from weight
He knew that I am confused so he asked me to derive it's
dimension I derived then he asked me to derive the dimension
of force by area and he asked me to compare, and I found my
mistake. I said sorry and then
He: I am giving it "Q" all the boundaries are insulated so
that no heat goes outside, calculate it's final volume?
Me: I was confused and was asking about a lot of irrelevant
information needed to solve.
He: This is all I told you now calculate the volume...no
other information.
I could not derive it.

Then......Fluid:
He: I am having an wedge shaped vessel (triangular shaped) I
want to know the water level at different places, what will
be the levels of water at different tubes?
Me: Same level in every tube.
He: why?
Me: because of fluids property...pressure at a level is same
at every point So the height raised will compensate for it.
He: ok so, pressure is constant at all the points in same
level but different at different levels?
Me: Yes sir.
He: So if I make two holes at different levels and fit a
tube at outside from the vessel then water will flow?
Me: yes sir.
He: If I place a turbine in between the pipe then will the
electricity produced?
Me: No.
He: why?
Me: because water will flow once only.
He: but pressure difference is continuously acting at two
different levels?
Me: as once water flows and the section gets filled pressure
at the same level in vessel and pipe will be same, So no way
it will flow again.

This was a section where I was somewhat comfortable and
answered correctly.

SOM:

Shear stresses, how shear stress comes ....Is bending stress
and shear stress same and a lot....they make me totally
confused.
Mohr's  Circle related questions. That I replied correctly.

Seeing six sigma

2012-02-04T07:15:00.000-08:00

By getting up close and personal with their digital prototypes, U.S. Army engineers have stepped up Six Sigma implementation and virtually done away with the need for hardware prototypes, saving millions of dollars in the process. Design engineers at the U.S. Army’s Armament Research Development and Engineering Center—Rock Island have developed a design method that relies on visualization and virtual-reality technology to immerse engineers in the design of U.S. military vehicles. The new method, dubbed the advanced visualization process, or AVP, has delivered significant cost and time savings to boot, to the tune of up to $4.4 million and 3.8 years as compared to the same project completed without AVP. That process, which moves designs from concept to finished product without hardware prototyping, calls upon a systems engineering method based on Lean Six Sigma principles, said Joe Kleiss, a Navy veteran and project manager for the Armament Research and Development Engineering Center, or ARDEC, in Rock Island, Ill. Kleiss began AVP in June 2005. He had received training in Six Sigma principles; then he had a light-bulb moment: Six Sigma and computer visualization technologies could be a natural fit. Via the technology, AVP brings together all design disciplines, decision makers, and end-users early in the design process, he said. “The ability to see digital prototypes early on and modify them iteratively provides a way for each of these groups to contribute to the end system design from the very beginning of a project,” Kleiss said. One big element of the AVP is the Immersive Engineering Laboratory, which uses a CAVE, a room-size virtual reality system in which users can interact, hands-on, with three-dimensional digital prototypes of systems.

No meaning of catastrophe(pralay) in 2012

2011-12-25T10:33:00.000-08:00

hi,,
frnds one thing i tell u that there is no meaning of catastrophe(pralay) because according to maya calendar all media and newspaper says that pralay comes in 20 dec 2012 .But this also possible that in maya calendar only till year 2012 astrology are given. so don't worry about this matter because this is not true,so be happy and enjoy.
