How would you act in this situation?


I just had a job interview on the phone, and the person who interviewed me assured that a responsible person would send me an easy logic test or smth similar. It seemed that she was serious about the next stage (an interview in person), so I got quite excited thinking I had made it through to the next round… However, it’s been like 2 hours after the interview and I didn’t get any test neither a call. Has anyone had a similar experience? Is it common for the interviewers to act this wway (talking in such a way that they make you believe you got the job and then… nothing?). Would it be polite to call her and inform that I didn’t get anything and therefore I wonder if some service problem occurred? Feeling so nervous… Thanks in advance for any suggestions.
