EPAM Systems Data Engineer interview questions

The interview was for 1.5 hrs, however, it wrapped in 32 minutes. Didn't receive a response yet. Waiting for next steps. Normal project discussion followed by 1 python coding question

No proper interview has been scheduled so far. Multiple people have been calling every day to collect my details, but there has been no further communication or confirmation regarding the interview. I would appreciate it if the process could be streamlined or if I could be informed about the next steps.
