Cafe Gratitude interview questions

The interview process was standard and the interviewer was punctual and efficient. Only one interview needed. The interviewer focused on talking about my experience using the computer system they use. However, when they later ordered me the job, they offered less than was listed in their job post, so I declined. They claimed the amount listed in their job post would only be offered to me after I worked for them for years. I was frustrated for wasting my time.
