Competency based interview which aims to determine if one is the right candidate for the role by getting an understanding of how one would apply themselves in real life scenarios

Travelling all the way to Changi bussiness park & interview with one HR physically, 3 managers remotely via zoom meeting. Why not just arrange an online meeting since 3 out of 4 are not even here physically. And when I show my rewards & certificates, managers are trying to say I’m not good enough, if I’m not good enough why am I even getting this interview chance? They just want to lower your salary & expectations. Just be confident, you are good.
