Each nitrogen atom has one lone pair and forms three sigma bonds (one with a carbon and two with hydrogens, assuming a typical valency completion for neutral molecules), making it sp2 hybridized. Each carbon atom forms four sigma bonds (two with hydrogens and two with the adjacent carbon/nitrogen), making them sp3 hybridized. Therefore, no atoms in this structure are sp hybridized.
