It it’s a colleague, I’d limit my exposure. If I am manager, I wouldn’t hire such a person or fire asap. Inability to process indirect and nonverbal communication - aka 90% of human communication - is a major energy sap and drag to anyone interacting with this person. The thing that only responds to explicit verbal instruction is called a robot. When hiring, people expect to be hiring a human with good (albeit ineffable) judgment, not a robot with blank slate.
