I am currently employed as an intern, and although it was mentioned to us by a few employees including the HR itself that there is a possibility of upskilling to a different capability should there be an opportunity, I haven't had the opportunity to explore that myself.
Showing appropriate results and have the ability to work with them will grant you a chance to be absorbed and a full-time employee
Being an intern, the primary opportunity for promotion available to me is the possibility of being absorbed into a full-time position. The firm offers a worthwhile learning environment, and acing the internship can lead to long-term job opportunities, which suit my career goals perfectly.
