"I know Julien, he is a computer scientist."

Translation: Je connais Julien, il est informaticien.

[patfinegan]

"Je connais Julien, c'est informaticien" was marked wrong. Why is "il" required instead of "ce"?

[Sitesurf]

When stating someone's profession with the verbs "être", "devenir" or "rester", the profession is used as an adjective:

• Julien est informaticien
• Il est informaticien

The alternative with "c'est" needs the profession as a noun and therefore an article:

• C'est un informaticien

That helps immensely. Thank you!

can't one use the word savoir as well as connaitre

[Sitesurf]

Not with people and places, with the meaning of "to be familiar with".
