Yes and no. They have much of the same responsibilities and similar education for 2-3 years in college.
An engineer is a problem solver.
There are different engineering disciplines=mechanical, industrial, civil, military, aerospace, aeronautical, electrical, marine, controls, mechatronics, electronics, chemical, bio, biomedical, environmental, energy, agricultural, and more.
All of them exist to solve problems in this world related to their field of study. They all plan, design, develop, improve, and sustain systems, whether they are cars, planes, dams, bridges, buildings, waste management, sewage, water and air, environment, ecology, biodiversity, medical equipment, prosthetics, furniture, HVAC, plumbing, circuitry, or software.
All engineers are identical. If you ever go to a party hosted by an engineer, you will observe that each engineer looks exactly the same as every other engineer, tells the same jokes, laughs at the same jokes, and eats the same food. This phenomenom occurs because engineers are essentially the lowest energy state of a Bose-Einstein condensate, in which each particle (engineer) is identical to every other engineer in the condensate.
Mechanical engineers design weapons.
Civil engineers design targets.
Let's see. You ask if all engineers are the same then what are the differences. Gee, if they are all the same then there are no differences..
The fact is, all engineers are different just as all doctors and all lawyers are different. People are just made that way.
The engineering profession is often divided up into different disciplines: mechanical, electrical, chemical, environmental, software, aerospace etc...
Often, the same mathematics is used (ie: 3D vector calculus) to solve different problems, by renaming the variables.
There are dozens of types of engineering degrees available from many different colleges and universities. Obviously having an engineering degree that is exactly in the field that you are seeking a job is the ideal. That said, just having an engineering degree should make you employable in other disciplines as well.
I have a good friend that has a degree in electrical engineering but all of the jobs that he has had are in software. Go to school and study what you like. With a professional degree you should be OK but you will need to be flexible.
Good Luck in your endeavors!
Engineering has its specialties.
How you work:
Design, test, quality, sustaining, industrial, manufacturing, etc.
What you do:
Electrical, electronic, structural, biomedical, aeronautical, aerospace, mechanical, etc.
If so what are differences
