Hello.... Yes, engineering grads can get into Sales & Marketing (S&M) function very easily. Engineering grads are required specifically to sell specialised products such as Chemicals, Aeronautical, Information Technology, Automobile etc. Manufacturing companies like L&T, Carborundum Universal, TATA, Schneider, BMW, Nestle, HAL etc are all examples companies that recruit Engineering grads for their S&M function.
However, for S&M role, additional attributes such as excellent vocal skills, extrovert nature, natural curiosity, comfort with interactions & being with people, willingness to travel are beneficial to perform well.
