Bdl interview experience
1) Introduce yourself
As I included my college projects
One thermal management and other automated waterless solar panel cleaning in introduction so they asked about
They asked how it works
What did i use
As i used arduino
Microcontroller vs microprocessor
It’s limitation , why did you use IR Sensor , other than cleaning of solar panel where it can be used in other place like how it can be useful in bdl , what is lead screw
Then they asked about my favourite subject area
I told them heat transfer then they asked about what is nozzle , draw different type of nozzle ,types of flow in nozzle
What is mach no.
What is generally the mach no. Of fluid coming about of nozzle
Converging diverging nozzle
And question related to it
What we call when mach no. Is less then 1
Draw stress vs strain diagram of ductile material and label it
What is significance of yield point
What is necking
Mostly question they asked were about my project initially
Interview lasted about 10 to 11
Most of the interview were around 10 minute but some were about 7 -8 also

Hello everyone, I've created a separate group for those interested in investment and learning through live sessions. You can join this group to keep discussions focused; this current group is only for engineering updates.
In the new group, I'll share investment-related information and conduct live sessions. If interested, join via the link I'm sharing 😊. You're welcome to share this with your family and college groups as well.

Namste Sirji🙏🏼
Here is my BEL interview experience.
1)Introduce yourself
2)Justify why not working since almost 3years?
3)What are your strong subj- I said. Thermo HT, FM, RAC, SOM.
4) Define various processes in thermodynamics.
5) Is there any process where we can manufacture a product without material removal.
6) Explain additive manufacturing
7) Explain Lapping process? Why it's needed
8) Micron to mm conversion
9)Maximum material limit for hole and shaft draw the diagram as well.
10) Why we study Metrology.
11) What is latent heat and specific Heat?
12) Is temp constant during latent heat and phase change.
13) Among a solid shaft and Hollow shaft which one you will use to handle more stress. And some follow up questions on same topic.
They were not asking what do you know about BEL, BEL website, products and all nothing. Not only for me everyone had same experience. Just you have to have strong reason for year gap and technical knowledge HR questions jayada nahi pucha.
Thank you sir🙏🏼
