This pattern alone is absolutely not enough to suspect it's ADHD. Several other factors need to be present.

In general during diagnosis (I can attest to Germany), it must be credibly shown that multiple symptopms have been present both during child as well as adult age.

Typical patterns are several aborted apprenticeships or studies, inability to hold steady employment over several years, problems with romantic relationships or long lasting friendships.
