Literal
She [topic-は] lawyer became [the moment-途端に] old friends [object-を] try-to-look [even-も] didn't.
~途端に marks the instant transition — 'the moment she became a lawyer.' 見向きもしようとしなかった stacks negation: 見向き ('a glance') + も ('even') + しようとしなかった ('didn't try to do') = 'didn't even try to glance at.'
