Sodexo Finance Controller interview questions

It seems such a smooth process at first but even after clearing two rounds of interviews they said no because of the pshycomatrics test which they asked me to appear. And after 4-5-6 days and after my follow ups, as per them test result was not satisfactory. I got the point, in the meanwhile they got another candidate who agreed at lower compensation. But I don’t understand why they don’t come and straight away tell us that they can’t meet our expectations. Thats so simple. And that won’t be demotivating atleast
