Amadeus Manager interview questions

I interviewed at Amadeus Singapore in 2024 and was invited to attend all stages of the interview. I did not receive a call back so I assume my application was unsuccessful. Unprofessional hiring team as they don't even have the basic courtesy to inform the outcome or is it just they way they work? As an MNC, they need to start from basic and review their processes to get it right and think before they act.

Es un proceso largo con varias entrevistas y un caso práctico complejo para el cuál te dejan media hora de preparación para posteriormente realizar una presentación a los entrevistadores y atender a sus preguntas.
