I applied for the intern position at PwC office in Moscow, Russia. For this position it takes three steps:
1) Four tests (Engilsh, Russian Accounting Standarts, Numerical Reasoning Test and Verbal Reasoning Test)
2) Interview with HR-specialist
3) Interview with managers of your future department
If you pass one step, they invite you to the next one. All HR-girls are super-nice and attentive, although you might wait for their call with the answer for a week or more.
A few words on each step:
1) English test is not difficult at all, if your level is intermediate at least. To pass the accounting test you have to know the basics of Russian Accountancy and the basic transactions. Information about the numerical and verbal tests can be easily found online.
2) HR-specialist asked me questions about my personality, character and personal qualities. And why I chose PwC, of course. All those questions can be found in "Interviews at PwC" on glassdor.
3) Managers asked pretty much the same as HR, plus couple of professional questions (I think it depends on the department). And they provided more information about what their department does, and made sure that I'm ready for the long hours and for the lots of work.
