Two chart schools may start in different places. One may examine the Career Palace through its supporting structure; another may begin with the Origin Palace and transformations. Before comparing their conclusions, define the event: failure to get an interview or difficulty after starting work. Keep the birth input and school rules fixed, record each reasoning path, and check it against dated events.
The starting palace depends on the question and the charting school. First check birth data and chart settings across tools. A career question and a housing question should not share one assumed starting point. Record the main palace, opposite palace, supporting palaces, and the transformation rule used.
