assessment strategy

Been called twice to attend assessment for capitec bank, and having done similar job one would think once have received a call for assessment chances of passing of passing it are high. With lots of practice on computer. It a different story when reached assessment room, the strategy they use make u feel dumb and not worthy of being employed. Egency not friendly and doesn't inform what she expect in order to be pass. Which they seem so easy but will still says u have failed. I mean questions are based on experience.
