As far as I understand, EU schools have high regards for PhDs from anglosphere, especially from USA and UK.
But, what about schools in EU itself?
Suppose, an International student,
(1) has a bachelor, Masters, and PhD from a same school "X" in an EU country "A".
(2) has a bachelor, Masters, and PhD from various schools "X", "Y", and "Z" in different EU countries: "A", "B", "C".
Does (2) make any difference if he has an intention of doing job in a school "X" as a teacher?
Do schools/universities in EU prefer to appoint PhD graduates from their own student pools?
