I think the MBA (Master's of Business Administration) degree needs some discussion because it is a somewhat unique master's level degree as compared to other master's/advanced level degrees.
In fields like law, medicine, and engineering, it is very common to go immediately from undergraduate to graduate school. Starting around 1990, this changed for most MBAs. The 1990s is when most MBA programs started to put in a requirement for having had work experience in between completing a bachelor's degree and starting an MBA program. Most MBA students have somewhere between 2-10 years of post bachelor's degree work experience, typically falling in between 3-7 years of post bachelor's work experience.
There are also 3 different groups that pursue MBAs.
1. The usually struggling liberal arts/social science major
This group received a bachelor's degree in some liberal arts/social science major and hasn't been doing too well in the workplace. They are getting an MBA to enhance their career outcomes. Without the MBA, they are destined for mediocrity if their undergrad degree wasn't from an elite university.
Alissa Heinerscheid, the former VP of Marketing for the Bud Light brand, fell into category as an MBA student. She had a liberal arts degree from Harvard before getting her MBA at University of Pennsylvania's prestigious Wharton School of Business. The difference between Heinerscheid and most of Group 1 is that most of Group 1 has their undergrad degree from a non-elite school.
Despite her 2 Ivy League degrees, Heinerscheid's legacy is destined to become the marketer who irreparably damaged the Bud Light brand. She's only 39 years old right now. If she's able to get another job in Marketing in the private sector without a political affiliation, it's likely to be a step down.
It's a common path for undergrad liberal arts Ivy Leaguers to end up getting their MBAs at Ivy League schools.
2. The business major
This group has a bachelor's degree in Business Administration, or some adjacent area like Economics or Accounting.
In most cases, this group would be more employable than Group 1 in the absence of an MBA. This group will see a benefit to their careers from their MBA, but it is less essential for them.
3. The STEM major
This is typically someone with an undergrad degree in Computer Science or Engineering, though it could be a Mathematics major.
This person is getting the MBA to move more on to the business side within companies with a STEM orientation.
This group is really focused and benefits a lot from the MBA, though they often have a strong undergrad degree and some good pre-MBA work experience.
