<p>My second statement is not just an opinion. </p>
<p>In specific cases (such as yours) one may be successful with a little bit of knowledge of various engineering subjects.<br>
However, in general, one needs to concentrate and specialize in a particular field to maximize the chance of getting a job. If you look at the engineering job adverts, the overwhelming majority requires graduates from a particular field. You may have found an opening now, but employment situation is always in a flux. You have to go with the trend in the job market.</p>
<p>My father has worked in the engineering field, has taught in the engineering college, and his advice to me is to go to a school with specialized engineering departments. The engineering work is getting to be more complex by the day and, therefore, specialization is needed. One has to get MS and PhD in the particular field to advance on the technical ladder. (It is the same thing in medicine. A generalist won't cut it, the medical doctor has to pick a narrow field and study it at great depth.)</p>
<p>Another place with a general engineering dept is Harvard. They claim "Students pursue work on a variety of topics, such as electrical engineering and bioengineering." IMHO, a kid who has the credentials to go to Harvard is better served to go elsewhere (Stanford, MIT, CIT, Cornell, etc) for the engineering degree in a specialized field.</p>
