First started with numerical test. Second, chit chat interview getting to know you better. Third, case study. You were given 90 minutes to analyse and prepare, follows by next 30 minutes to present. I believe there will be another next stage of process, but mine just stopped at case study

Standard HR screening followed by a hiring manager and panel interview. While the initial stages were professional, the experience was ruined by complete ghosting after the final step. It is disappointing to reach the end of the process and receive zero feedback or even a basic decision. This seems to be a recurring pattern in their recruitment hygiene; my application status was simply changed to inactive in the portal 4 months later without any contact. If you interview here, be prepared for a potential black hole after the final round.
