To utilize the variables defined within the Azure Pipeline interface as the job name or displayName, you need to use the syntax ${{variables.variableName}}. For example, if you have defined a variable named jobName, you can use it in the job name or displayName like this:
jobs:
- job: ${{variables.jobName}}
displayName: ${{variables.jobName}}
steps:
...
This will set the job name and displayName to the value of the jobName variable.
