phone interview with hiring manager, in person assessment center, expected to get feedback within a week as this was what they communicated. took over 3 weeks. really bad communication which ruined the experience (aka no communication at all). had a case study to prepare however was not easy as you could hear other candidates give presentations in the neighbour room, you could hear hr + hiring manager talk about it, lights went constantly off, HR said they are in the room next door if help was required which was not the case, as i checked 3 times. received a calculator that did not work which made it impossible to come up with good data. my suggestion - bring your own calculator just in case.
