„Haben Sie Erfahrungen im Service?“
Frau Jansen fragt Ibrahim, ob er Erfahrungen im Service hat.

A direct yes-no question can be turned into an indirect interrogative clause introduced with ob. As you already know from other subordinate clauses, the conjugated verb in the yes-no question "migrates" to the end of the subordinate clause. Be careful: in the indirect question, the perspective is often switched, affecting the person or personal pronoun.
