Gordon Ramsay Holdings interview questions

Interviewed with the group wine coordinator. Absolutely shocking and unwelcoming to the point of being rude. Zero questions about the company or wine and some misunderstood conversations due to poor English. The salary offered changed twice throughout the recruitment process showing complete incompetence. I was sent a legally binding written offer of employment, then it was retracted by telephone the next day, then i was offered another position within the group. This was the most disappointing and unprofessional interview i have ever had. I tried to contact the group through the website to leave my feedback with no reply.
