Preguntas de entrevista para el cargo de Senior Python Developer/Software Engineer en Stack Builders

- Email from HR to schedule an initial interview. - Then initial interview with HR 45 min to 1 hour including 2 employees from Stack-builders team. - Then another technical interview (1 hour) with many questions related to python and REST . - Then I received an email : not selected for the position with no feedback .. They mentioned they are : (one of the leaders within our industry) Do not know what to say , I was just wasting time .. I expected they respect the time when they said in the first interview that they are not hiring for a client but hiring in their team and the process is super fast (1 week max) and they are not intending to waste time !!!
