Quite negative overall. Multiple stages (which seems to be standard) - 1. intro call with a junior employee, 2. case study assignment, 3. call with a senior employee to discuss the case study, 4. call with CEO. Passed all stages, put in quite significant effort and time to prepare the application including cover letter, do the assignment and go through all calls. Received a rejection by getting a totally generic email not stating any rationale, including 0 feedback. Asked multiple times various people to provide some feedback to see what to improve with my application - complete silence, ignored. So overall rejected and ignored despite putting in significant amount of time and getting positive only verbal feedback before. Seems quite irrational and does not look like they treat people well.
