For the past five years Maskoliunas has served as assistant coach of Zalgiris' Sarunas Jasikevicius. He has experience of working with the national team as he assisted Jonas Kazlauskas when he head-coached the national team in 2013-2016.

Maskolunas is facing the first test in February when the national team will join the EuroBasket 2021 qualifiers.

However, the Olympic qualification will pose the biggest challenges as the Lithuanian team will try to become the group's leaders and qualify for the Tokyo Olympics.
