Deloitte SAP Consultant interview questions

After I applied online, a recruiter contacted me & asked me about my background, expectations etc and said I would be contacted to schedule a technical skills interview. The technical interview took place over the phone a few weeks later & there were around 4 people questioning me one after anothre on different technical topics. After that it took Deloitte about 2 months to schedule a personal interview which was purely behavioral/situational type questions with first a senior consultant then a partner. A week later I was offered the position. They don't book flight/hotel for the personal interview upfront, the candidate has to meet the expenses & later submit original receipts in a postal envelope. They don't accept copies of receipts or scanned expenses sent through email either. Expenses are reimbursed after 1.5 months. Their background check process took a lot of time, around 3 months which comparing to other big 4 companies is very very slow. Overall their recruitment process is very slow & their recruiter or the 1-800-consultants don't have much information about the company policies or procedures when you call them with any queries after you have the offer, everyone seems confused & has a different answer.
