Worst interviews process ever, after going through all technical interview the HR interview was worst. The HR are not professional they will simply waste your time you have invested in overall interview. They will not give you offer letter even though you have clear all round. Don't fall in trap with such unprofessional company.

Just go through the CV from the latest job experience to the earliest. Plus a further talk on personal interest and background. There were 2 round of interviews within them before arranging an official interview with the hiring company.
