Very simple interview, small questions about yourself and how you can work as a customer support representative

Lies. I went for an interview for Customer Support Representative which is a full-time permanent position, but when I got in there I was going to be interviewed for a totally different role (QA Localisation Tester), which is a zero-hours contract. When I explained I was looking for that particular position, the interviewer told me the vacancy was filled and tried to explain to me they've made internal arrangements, which I think is not honest for such a big company. My guess is that they advertise permanent positions just in order to get more candidates applying for, but what they really want is people working only for the specific time they need at the moment. I had a short experience before this episode working for PTW as QA Tester and never got enough hours in a week. I don't recommend this company if you are looking for stability.
