The hiring process consists of 3 steps:
As a first step of application, you have to fill in an online questionnaire including 9-10 (more like personal) questions, such as: what is your greatest achievement so far? what do you do in your free time? What motivates you?...etc.
If it is ended up in a successful evaluation, you are invited to a one hour one-to-one HR interview, where you walk through on your CV and additional general questions may be arisen, too. It is a good point and 'required' to ask questions regarding the position you have applied.
As a next step, you get an Assessment Center invitation, which involves the followings: 3 tests (English test, Verbal and Numerical tests), one-to-one inetrviews with a Manager and a Partner (one in Hungarian, the other in English), situation practice with HR colleagues and a team situation with other candidates. Those candidates, who are successfully completed the above described 3 steps, get an offer :)
Personal recommendations during the interviews: Be honest, and be yourself! Not afraid of asking questions, you are interested in. They appreciate it.
