The UC Irvine guard made the jump from the U20 programme to head coach Joe Prunty's senior set-up this summer and followed an impressive debut against New Zealand with appearances against the Netherlands and Portugal.
The 21-year-old was one of nineteen players invited to work out at national team camp in July, prior to being named as one of the twelve selected to face New Zealand at the Copper Box.
"It felt really good to be called up to the senior team's camp and get the opportunity to be there and to be a part of the programme," said Young, who had four points, six rebounds and three assists in his 25-minute debut.
"I was excited when I was selected to play against New Zealand because it just meant that my week of hard work had paid off and Coach Prunty thought that I could be a good part of the team.
"The experience of playing at the Copper Box and getting my first cap was really special and fun.
"To be able to represent GB is a great honour," added the guard.
Young's performance, attitude and application earned him that privilege for a second and third time, when he subsequently travelled with Coach Prunty and a fresh-faced roster to take on Portugal and hosts Netherlands at an invitational tournament, in Leiden earlier this month.
After a narrow defeat against the EuroBasket-bound Dutch, Young lifted GB to a win against Portugal as he scored 16 points and grabbed seven rebounds in a 76-66 success.
"In the Netherlands I just really wanted to be aggressive in the game against Portugal, because I know that's the type of game I am capable of having," said Young.
"My team-mates and coaches also just told me to play each and every play and look to score and be aggressive.
"Getting that win was great for us moving forward."
Great trip out here to the Netherlands! Great experience and things to learn from. Until next summer???- Alex Young (@alexyng1) August 16, 2015
Young's own development appears to be moving ahead at a rapid pace too.
He was a key part of Douglas Leichner's Great Britain U20 side that achieved a best-ever 11th-place finish at the U20 European Championship last year, averaging 11 points, 5.2 assists and 3.9 rebounds-per-game along the way.
That was followed by a historic maiden trip to the NCAA tournament with UC Irvine last season, alongside GB U20 team-mate Luke Nelson.
Young is in no doubt that his experiences at U20 level prepared him for the next step on his climb up the basketball ladder, and sees no reason why that ascent should slow down anytime soon - now he has another successful summer under his belt.
"Playing with U20s was a huge help preparing me for the senior team because it allowed me to get used to how the game was played in terms of the FIBA rules," revealed Young.
"Obviously the difference playing with the senior team was playing with and against guys that were older than me and already playing professionally."
He added, "Making the NCAA tournament last year was the greatest part of my basketball career so far.
"Going into my last year I expect to go back to the NCAA tournament and make a run, because I think we have a team capable of doing that."
