I think a lot of Harry Potter fans would agree that it's hugely disappointing that we'll never get the opportunity to apply for jobs in the wizarding world. Whether you'd want to be fighting baddies as an Auror, a Magizoologist chasing magical creatures, or even a Gringotts bank teller working amongst the grumpy goblins, it all sounds pretty awesome.
Heck, I'd even spend my days behind a desk in the Office for the Detection and Confiscation of Counterfeit Defensive Spells and Protective Objects if it meant working under Arthur Weasley.
Since I'd be highly unqualified for these jobs even if they did exist, I think they'd be better suited for people like Harry, Ron, and Hermione. In case you've ever wondered what happened to the Golden Trio plus friends after they left Hogwarts for good, here are some awesome fan made Daily Prophet posters made by DeviantART user Nhu-dles who has a few ideas, paired with what we know to be canon from J.K. Rowling.
What kind of careers struck the interest of the Hogwarts alums? Let's find out!
After defeating Lord Voldemort in the Second Wizarding War and proving himself more than capable, Harry Potter became an Auror under the new Minster of Magic, Kingsley Shacklebolt, without having to get his N.E.W.T.s. Yes, Harry is technically a Hogwarts dropout! Then, at 26 he became the youngest ever Head of the Auror department where he helped revolutionize the department at the Ministry of Magic.
Hermione Granger, unlike Harry and Ron, returned to Hogwarts to attain her N.E.W.T.s. She then earned a position at the Ministry of Magic, first in the Department for the Regulation and Control of Magical Creatures where she continued to work on her S.P.E.W. campaign and advocate for the rights of underserved non-human creatures. From there, she moved into the high-ranking position of Deputy Head of the Department of Magical Law Enforcement in which she aided Minister Shacklebolt in eradicating all antiquated anti-Muggle laws, revolutionizing the wizarding world.
As this piece of fan art shows, Ron Weasley also became an Auror where he worked alongside Harry in the department for a few years. Later in life, he left his job at the Ministry to to help George run Weasleys' Wizard Wheezes. Despite his many successes, what Ron considers to be his "finest hour" was when he, Harry, and Hermione were featured on their own Chocolate Frogs cards.
After concluding her studies at Hogwarts, Ginny Weasley played professional Quidditch for the Hollyhead Harpies as a Chaser for a few good years. After retiring from professional Quidditch to start a family with her husband Harry, Ginny was hired as the Senior Quidditch correspondent at the Daily Prophet.
By the end of the Battle of Hogwarts, Neville Longbottom's bravery and courageousness was never questioned again. He joined Harry and Ron briefly working in the Ministry of Magic as an Auror before being invited back to Hogwarts to fill in as the Herbology Professor.
While this image isn't canon, it's certainly a nice thought. Luna Lovegood went on to follow her love of magical creatures and became a Magizoologist (magical naturalist) alongside her husband Rolf Scamander, grandson of famed Magizoologist Newt Scamander. Although she was able to uncover many mystical and lesser-known creatures, she never did find a Crumple-Horned Snorkack.
Again, Draco Malfoy becoming a banker is not canon, but it might as well be since he spent so much time around money. Given his family's mass wealth accrued over generations, Draco Malfoy never really had to work. Instead, after inheriting the Malfoy Manor, he focused his time on continuing to collect and maintain his family's collection of dark, ancient artifacts and studying alchemical manuscripts, but only as hobbies.
Thanks to Nhu-dles for their awesome artwork. If these happened to be real magazine covers, I'd be sure to buy a copy or two!
