Sudden rejection with generic email out of nowhere, although everyhting seemed fine so far, hence the negative rating, because it is just too inhumane / robotic given the process so far, and I demand better of a company. Very likely due to cost-cutting / lower salary/self-respect competitors, so keep in mind this is the same respect / lack thereof you would get from the company once employed, Other than that, the typical Angular Spring Boot questions, annotations, scopes, Java coding, modifiers etc.
