Capgemini Invent Energy Consultant interview questions

Really awful recruitment process. Went a month between each chat or interview after being told i would hear back in a week. Had to follow up each time which was difficult as dealt with a different person each time. Not hard interviews. Made it to the TSE event where I was told the wrong time and had booked annual leave. The recruiter did not seem to care at all and sent very casual and unprofessional emails. Slightly confusing presentation process. Rejection notes had not been formatted at all.
