This question feels like a trap. It's not.
Don't: Get defensive or apologize
Do: Reframe what you bring that CS grads don't
Strong answer structure:
Acknowledge the technical gap briefly
Highlight your unique value
Show you're closing the gap
Example: "A CS grad has years of theory I'm still learning. But I bring years of working with customers, understanding business needs, and shipping under pressure. I'm closing technical gaps through focused study, and my professional skills take years to develop."
Career Changer Tip: Never say "despite my background." Say "because of my background."
