Preguntas de entrevista para el puesto de Systems Developer/Python Developer en Calsoft

I was called at 1 O'Clock, I reached there in time. They told to sit us near the desk's where chairs are broken(Pathetic Experience). HR came after 1 Hr to take resume (Unprofessional). After Waiting around 4.30 hrs and continues follow ups from HR called me for an interview @5.30. One Interviewer was taking interview of two candidates simultaneously (Very unprofessional ) Started up with basic questions then advanced ones- Answered. Told to write code snippets - Wrote. Draw current project architecture - Drawn and Explained. Everything goes well, after waiting for around 20 mins HR conveyed me that they are decided not to go ahead with my profile. Very much Disappointed with process.
