Talent Preneur Management Consultancy interview questions

The feeling was not good, their website show few different companies they have owned. When I tried to ask which company that I'm going to interview for. No one can answer. There is an "old man" like owner has interviewed me for 2 hours but in that 2 hours... he is the one who talk much. And persuade me to work as Sales and show me the sales results data of their employee. Totally not professional.

3 rounds of interviews. The 1st round is relatively "normal" by the HR function. The chairman requested 2 separate rounds of "final interview" and has asked for a lot of irrelevant info, even an intrusion of privacy, such as age of the candidate's parents, number siblings, children, any family related and caregiving obligations, political view, religion, etc.
