I sent my CV and cover letter, and was invited to a phone interview a week after. The interview itself was competency based and not so difficult. I was told in the interview, that the assessment centre would happen on a certain date so I kept the date free just in case. Three days before the assessment centre is due to take place, I still have not heard anything about the outcome. I send emails and calls to the company, however they are unanswered, finally I manage to get through to the HR manager who tells me my application has been unsuccessful. No feedback at all was provided, just a generic 'good luck with future endeavours'. Applicants should not have to hunt down a contact address in order to track the progress of their application. The experience overall was unprofessional.

Phone call for the first interview, mainly just fit questions but ended with a smaller case exercise just for them to evaluate your analytical thinking. After a week i was invited to their on-site interview for a full day. More behavioral questions, presentation, a full case and a technical assessment. Fun experience overall and everyone there was super nice and easy-going.
