adidas Big Data Analyst interview questions

I was contacted by Adidas via Linkedin. They were very interested in my profile (Big Data) After exchanging some emails, I got the first interview by phone (I am based in Spain and the position was for their headquarters in Herzogenaurach) Everything was ok, a very positive interview. Then they sent me a technical test, to be returned in 3 days max, which I did. Then, NOTHING. No feedback, no contact, nothing. I did try to contact them by phone, mail, linkedin… NOTHING Never heard from Adidas again. I have never expected a company like Adidas to treat candidates that poorly. The less you can expect when they contact you + you do an interview + you do a technical test is to have FEEDBACK.
