Tesco Customer Assistant interview questions

Filled in an application from online. Got a phone call a couple of days later asking me to go in for an interview in the store. Was then interviewed by manager and assistant manager. Felt more like a terror investigation than an interview. Questions were nothing like I had expected and quite difficult to answer even though I had appropriate experience. Would of thought I was going for a manager position, not checkout assistant. Both interviewers were friendly but did not make me feel comfortable and relaxed when answering questions.

Quite relaxed, they just went through my CV and why I think I would have been good at the role. I dressed formally (as you would for any interview really). After we were selected (post-interview), we had an introductory day which was very long and a bit dull but had to be done! This was simply about their core values as a company, our uniforms etc.
