There's a test included of technical knowledge about tax (VAT, PIT, CIT) and the logical and aptitude test (multiple-choice questions). I got to interview with the managers, the interview would focus on what I did in my last position, and the technical knowledge related to those. And even though there're some questions I did not answer well, they would provide some suggestions to improve my answers. Overall, good interview process, though I did not get the job :)

The interview process was quite relaxed, starting with a standard phone screen. This was followed by an on-site panel interview where I had the opportunity to meet several peers and individuals from various service lines.
