Co-op Customer Assistant interview questions

I applied through a form in store, heard back 2 or 3 weeks later to come in for an interview. interview was easy, just general chit chat about my CV and availability etc. got the job then and there, think they were really needing someone asap.

Online assessment then face to face. I was very disappointed in the interview. The interviewer asked the competence questions then just spoke the whole time. Didn't ask me much. How can you assess someone without finding out about them? Didn't get back to me on three occasions when I was following up and said he would and then texted me by accident rather than someone else he had clearly chosen and not let me know. Poor experience.
