There was a phone call partly Hungarian partly English just to confirm my language skills and previous work related experince and studies. Then I had to fill an online work attitude psychology test which I have passed. Third part was an onsite interview in the ECB headquarters in Budapest. The group leader and a HR manager were there. It was very easy, standard HR questions, standard work related questions. If you really want to work at Bosch you should be passionate about what you apply for! If you look like that you will get the position. If you have somebody inside Bosch ask them for referral, it helps a lot.
