A. If you do not have relevant work experience, then you can definitely mention internships in your statement of purpose. Moreover, if your internship was exceptional in terms of achievements, you should mention it in your statement of purpose. Please note that you cannot include everything in your SOP; hence, you must be careful in deciding what you wish to include and what you wish to exclude in your SOP. When you mention any internship in your SOP, make sure that you have adequate knowledge of what you have done in your internship. You should be able to justify everything that you have written in your SOP.
