The interview was not so difficult, I had a phone call with HR dept, then with a manager and Partner. They left me to talk about my self and my background, with normal questions (why Deloitte, why luxembourg); accounting question was about a purchase, then some question about audit process of receivable. I got the job. Good luck.
