It had three rounds- HR Manager - Techinical Round Partner round. HR here are very friendly and helpfull. Manager round was very insightful and a good process. Difficulty level - hard. Partner round was easy but tricky. Know as much as you can about Deloitte and let them know how you relate to Deloitte and its value. Also go through Accounting and auditing standards without which it will be tough to crack interview. Confidence is the the ultimate key. Have a good smile on your face.
