While attending
Sungkyunkwan University in 2015, Hwang was called-up to the South Korean collegiate national team for the
2015 U23 World Championship where his team finished in eighth place. Hwang decided to forgo his final two years of collegiate eligibility and declared for the 2016
V-League Draft. Hwang was selected first overall by the
Gumi LIG Greaters in the 2016 V-League Draft. Hwang was the first setter ever to be taken with the first overall pick in the V-League Draft. After the 2016–17
V-League season, Hwang was named Rookie of the Year. In May 2017 Hwang was first selected for the
South Korean senior national team to compete at the
2017 FIVB World League. He played as the starting setter in Team Korea's final game against
Slovakia and led his team to a 3–2 victory, though he was mostly on the bench serving as the third-string setter behind
Lee Min-gyu and
No Jae-wook during the competition. == Awards ==
