The take home exercise which you will be told takes just 6 hours to complete, takes at least a few days to produce something meaningful. There doesn't seem to be any appreciation for applicants time and it felt like I was being interviewed for a job very different to the one in the job spec. The interviewer clearly didn't even take the time to review my CV and maybe even the job description! The interviewer also cut the interview short as it seemed like she was in a rush to be somewhere else. So unbelievably unprofessional.
