SBS Devops Engineer interview questions

A very bad experience here. Their interview process is very worst. I cleared the interview, they called me after 1 hour and congratulating me that you cleared the interview. We will arrange an HR round the next day but when I called HR, She said to me that you are not shortlisted. That's the total waste of my time and efforts. But It's good because they are showing their reality during the interview they can fire also after joining, I got this feedback from my friends who are working in Sopra Banking Software.
