Gone are the days where a first class is held in such high regard
If you’re a cum laude but you have good mentors willing to teach and nurture, you can make it to a big international after a few years.
If you’re a summa but you end up in a firm that doesn’t train you well during your formative years, or get muddled with office politics by disgruntled seniors, you’re quite screwed
If you go international and end up in wrong team, also pretty screwed
