Tesco interview questions

Applied online the process took few days. I got a call from them inviting me to an interview on the next day in the store. I arrived 15 mins before. It was one to one interview and the interviewer was really friendly. It was kind of short, around 10 minutes, so I didn´t have a good feeling. She said she will let me know, if I got the job she will call me, if not she will email me. I got an email, where they explained that I wasn´t succesful.
