Finalis interview questions

It was kind of a long process for no offer. Recruiter screen, manager screen, technical coding challenge, system design, cross functional screen with head of product, culture fit with hr, then no offer.

5-6 Steps process, multiple interviews with different people. An long unpaid assessment and presentation. After doing 5 interviews, spending hours on an Unpaid assessment and presentation for them they just ghosted, the process feels unprofessional and they don't give clear instructions or feedback which doesn't feel right after spending a lot of time during the process. We spent 1.5 Months doing all the interviews and assessment and then a 1 month later received the standard rejection email from their HR platform.
