Since you seem to prefer attending an MBA now rather than waiting for more substantial work experience, you should play up what you CAN offer, not what you can’t. You have a fantastic GMAT score so you can prove you’ll be ready for the coursework, and you can certainly count your internships as work experience. Share what you learned in this work that is directly applicable to your post-MBA goals and emphasize why it’s important for you to get an MBA now, rather than waiting a few years. In addition to the school you list, perhaps look at UC Davis and maybe UCLA as a reach.
Best of luck,
