Supertal interview questions

Firstly i had a call with an HR team member Then a 1 hour technical interview After that HR called me and said they selected me and will go with me They verified my profile with my team members and previous company members Also signed the NDA ,even had a pre on board meeting with me and other selected candidates but didn't send the offer Rather told me the joining date On the joining date they said that they have dissolved the vacancy, extremely unprofessional

It was not much of Technical Interview. More of what have you done in past. And show us what have you done till date kind of interview. Interview was great.
