Nielsen Research Analyst interview questions

I applied and got an interview. I wasnt told when to complete the assesment they gave me which was all in polish and I had to google translate. On top of that the job I had applied to was offered to me for a 3 months contract. I then emailed HR saying if its ok to submit my test the next working day, he emailed me back very rudely saying the role has been taken even tough I was in the middle of stages. The culture from what I gather is not culturally diverse in the Oxford office and I am glad I dodged a bullet.
