Sure - But it all depends on what is the actual work experience is, and how you frame it in your CV. Running a highly profitable lemonade stand could be considered something interesting to add to your CV, if you frame it correctly :)
MBBs and other consulting companies pride themselves in having teams of diverse backgrounds. So your experience shouldn't stop you from getting an interview (for entry-level positions)
(PS: I have 2-year work experience in construction and a non-MBA masters prior to joining consulting)
I hope this helped.
