By motor glider I assume you are referring to the SLMG. This is a UK aircraft designation and under EASA, UK licences issued after 2012 will not be convertible to EASA licences, except perhaps NPPL-LAPL. Touring Motor Glider TMG is the European equivalent and up to 30 hours may be credited towards a CPL. Currently very few schools teach for the PPL (TMG). Employers will not be in the least bit interested in what you have flown so long as you are qualified to the level they require.
