They didn't even show up to the interview. They require a compulsory cover letter, so I wrote one spending several hours to produce something meaningful. They invite me to the interview and they did not show up. I followed up with 2 emails. no answer. So I understand busy work but it is a bit a counter sense to work to make the world a better place if there is this type of approach to candidate and this fault of respect on abusing people time. Not a great introduction
