First two evaluation tests are to be done. Those are related to your person and your expectations from the job. Shall this be successful and meet the company's expectations, you will be invited for a video interview, that lasts about 40minutes. In case the recruiters like you, you will further be interviewed per skype, afterwards invited to the office to spend there a day. I personally went through the video interview and was refused thereafter. The video interview wasn't pleasant. THere were 6 questions asked through videos recorded in advance. One of those questions was in English, the rest are in German. I liked that the recruiting manager is very responsive and it lasts not more than a week until one goes through the process. On the other hand, it is ridiculous that the company requires its employees to work overtime regularly.
