qln: b4 his job change, his core competence and position was
(perceived by me) mostly niche sap tech (not functional) expert, not
primarily a presales cos presales is mostly functional.

ls: b4 his promotion, his core competence and position is (perceived
by me) mostly a niche product expert, not presales. I probably have
more leadership xp, wider xp, more mainstream skillset

How different after a single change!
