Note that the UCB MET program crams about 10 semesters’ worth of course work into 8 semesters (typically 20 credit semesters, as opposed to the usual 15-16 credit semesters) in order to complete the requirements for both majors.
However, students should be aware that a second major in business may be seen as a negative by some engineering employers looking to hire entry-level engineers, since they see it as a signal that the applicant is more interested in a fast track to management rather than doing high quality engineering work. @HPuck35 has posted a number of times in the engineering major forum section about his/her (negative) experience with such engineering + business graduates.
