Tesco interview questions

Filled out an online form and got an interview a few weeks later. The interview was quite easy however they lied to me in the interview. Having been told I would start after my exams a month later they called me a week later to start work immediately. I had no choice but to refuse the position.

I applied online and received a phone call just over a week later asking me to come for an interview which I did 4 days later. You filled out availability sheet and they asked you 5 scenario based question, talked about you would get from Tesco then I was took to the shop floor and put with someone who worked there an basically followed him around for 10 minutes to get a feel of what it would be like to work there. I went yesterday for my interview and was told I would be contacted by the end of the week.
