Introduce yourself, after introducing my self they asked me about my hobby, I have many certificates so he asked me whether I play any sports. And they asked me about Kabaddi( Kabaddi Is my favourite Sport). After that they asked me what's your favourite Subject in mechanical engineering. They advised me to write it on blackboard. After that first they asked me about thermodynamics. What is work and heat, what is first law of thermodynamics. As I told them answer they asked me deep and deep. Example :- what is heat? Why heat flow ? What is the law which governs heat flow in 1 D and 2D. Why heat equation is written in Negative in one side? Etc. After that Thermo, they asked my about IC engine. As I have written my 2nd favorite IC engine. What is difference between Diesel and petrol engine? Example of petrol and diesel engine. Which engine has more power? Why marine ship used Diesel engine? Which engine has more tharmal efficiency and why? What is scavenging? After this they asked me about mechanics as I have written Strength of material my favorite subject. They asked me which tyre has more friction between Wide and Narrow tyre. I said wide then they asked why wide I said Wide has more area Then I declined my answer And I said sorry sir Friction do not depend upon area. After that they asked my a thermo question again Suppose if you have two containers A and B And they have their different temperatures and pressures Now they are joined by a valve After some time What will be the final pressure and temperature? I was unable to derive it so they asked me Ok Just tell me final pressure will be more or less compare to both containers? They asked me what will be the Maximum moment when a simply supported beam is subjected to centre Laod? They asked me to derive it on black board! And asked me to draw Shear force and bending moment diagram. After that they asked me some very basic questions about core subjects I don't have remembered all the questions Because this interview was taken in 2019 . Thank You!
