Smart Energy Water Data Scientist interview questions

All rounds of the Interview went well, all Interviewers were very positive and I was also equally hopeful. In my view, all panelists were super confident about me but they didn't take my candidature ahead for no reason.

First was written Then it was technical. On video call. 2 person bombard questions mostly on what you have already done. Almost for 1 hr Another technical plus hr kinda round. 5 people were there asked n number of questions on project, why do you want to join, when ..... In the end even when everything went fine, they kept your application on hold, HR never respond on call or on email. Very unethical and unprofessional behaviour.
