"Work at" means to work for a specific business, company, store, etc. For example, I work at HayanMind. This means that this is the company that I am employed at. "Work in" means the specific field or service that the business provides. For example, I work in online English language learning. This means that the company I am employed at specializes in helping others learn English online. Ex: He works at the hospital. Ex: I used to work at the library. Ex: She works in the medical field. Ex: He used to work in retail but now works in broadcasting.
