The execution order of email rules is important. In general, there would be some basic rules that apply to all incoming emails to be executed first, then more complex rules that do specialised tasks, eg. create a job.
Generally, after running a specific complex rule, the execution of any further rules would be stopped by ticking Stop other rules if this rule is run.
Click Finish.
The execution order of email rules can be changed by selecting the rule, then using the Up/Down buttons to the right of the rules on the Email Rules screen.
