HF has a 4 rounds of interview process starting with HR interview, then an interview with some members of the team where they'll ask you some behavioural questions to understand you better, show you some data and ask for your interpretation, it's really interesting. After that a case study round where you prepare a case study on one of the topics related to the company and that also has an interview round where you present the case study and answer questions. If you clear this you have an interview with c-suite executive which will be the final round.
