Mechanical engineering final year students,graduates and even professionals, often stumbles to find a righteous guide towards acing their INTERVIEW or VIVA. I too as a student,gone through the same. In my 8+ years of industrial career,I have encountered numerous interviews and the ordeal that followed. So here is my effort to make it somewhat easy for you guys. I have compiled 100+ mechanical engineering INTERVIEW/VIVA questions which would surely help you out not only in acing interviews or viva, But also in strengthening your academics. 

If you are a mechanical engineering final year/Pre-final year student,A graduate, Or even a working professional, This course is meant for you.

More than a hundred questions are discussed from the realm of mechanical engineering.The course is designed in such a way that most of the major subjects are covered as such -

  • Basic Mechanical Engineering (BME)

  • Manufacturing Science

  • Material Science

  • Strength Of Material (SOM)

  • Theory Of Machine (TOM)

  • Automobile Engineering

  • Fluid Mechanics (FM)

  • Thermodynamics

  • Refrigeration & Air Conditioning (RAC)

  • Heat & Mass Transfer (HMT) & Many more. 

There are two answers for every question in the course -

  1. Explanatory Answer - Which contains relatively easy language & practical approach.

  2. Interview Answer - Bit theoretical (Boring) but can be considered apt while facing Interview/Viva.

The questions are divided into three levels - EASY,MEDIUM & HARD. However you might think a hard question as a easy one or vice-versa. In either case, You are always going to get one thing in return - KNOWLEDGE !!

PS - You will also get access to my book "100+ MECHANICAL engineering INTERVIEW questions" which is currently published on Amazon marketplace FREE of cost (The raw pdf format will be provided).
