I cleared the BHEL written exam and was called for interview. No GD. Interview was for the post of Executive engineer /E1 grade. It was a 10 minutes interview with 5 persons in the panel.Among them atleast one was an IAS officier.
Vaccant post : called candidates = 1:4 ratio. Loads of question were asked momentarily.Some question I remember are:
1) Take your seat.Why are you sweating? Are you nervous?
No sir. Actually… little bit. This is my first interview for a core company.(They smiled at me).
2) What is an IC engine and how does it work?
Explained from text book knowledge.
3) Difference between petrol engine and diesel engine.Why their milage differs.
4) What will happen to the room temperature if you turn your room in to a closed system by closing all the door and window perfectly and then you open the door of the room refrigerator that is in running condition.
Got puzzled.but answered as temperature of the room will increase since input is always greater than output of the system.
5)What actually entropy is? Explain me since I know only farming. 😉
I tried to explain entropy as a disorderness of a system without explaning any mathematical formula and interviewer nodded approvingly.
6)Tell me quickly ,Two co-cenric circle rolls together up to 3 mtr.Now tell me whether both the point has travelled same distance or not.
Its the perimeter they are travelling. So obviously different.
7) Explain how a human walks by using friction.What kind of friction is involved (static friction or rolling friction).
Answered though not sure.
8)What is dovetail milling.Why class 3 lever is used in reality.
9)What is the need of riser in moulding?
Explained riser as a checking process to confirm the molten metal has filled the cavity or not.but interviewer didnot agree indicating me for any other reason.closed my eye and took 5 sec and explained.
riser works as a backup reservior of molten metal when the cavity metal volume shrinks due to solidification.
Interviewer happily agreed.I was like 'God saved'.
10)Gave me a paper and pencil and asked to draw a carnot cycle and explain it.
Explained it.(never forget to give the directional arrow sign for any mechanical cycle.mind it.That is a test too)
11)Asked me bout posting preferences.If it is Ladakh will it be okay for you?
Had to agree by thinking I can drink coffee in the cold ;).Interviewer gave a strange look.
12)Why do you want to quit the biggest IT MNC since this sector is surging?
Told it honestly.Mechanical attracts me more and I will be surging along with BHEL.
After their whispering internal discussion they told "ok.you may leave".
There are thousand of question you can be asked to be judged.You need to be thorough with the text books first.Rests are presence of mind and your originality.
All the best.
