Examples: I am interested in something. (I would like to know more about the thing) I am interesting to people. (People would like to know more about me)

Hello Cappucci, The correct one here is : " be interested in someone" It means showing interest for someone. You could say on the other hand : " be interesting for someone"

"To be interested in smth" this is Present indefinite passive voice construction Construction of the Passive Voice The structure of the passive voice is very simple: subject + auxiliary verb (be) + main verb (past participle) The main verb is always in its past participle form.

somebody +be interested in sonething是正确的。 人做主语的情况下用-ed的形式。物做主语的情况下通常用 -ing 形式。
