Overall the questions weren't that difficult, but then she (manager) kept asking the same question over and over even after I gave the answer. Maybe it's the language issue, but then if that's the case we could've just done the interview in our mother tongue since we're both from the same country (I felt very weird why we're doing it in English since she's always stuck during our convo)... Moreover, her professionalism throughout the whole interview was questionable. She just sits down very unprepared, asking questions out of no where, and after having a few talk with her, I knew we wouldn't get along and even if I got the offer I won't enjoy my life there working under her. So yeah, thanking them for rejecting me.
