With default job management settings, one of the schedules would run and other would fail. The successful job would depend on how the schedules would be configured.

If the setting “queue conflicting jobs” is set (not the default setting) in control panel → Job Management, then both the jobs would start one after the other.

Hello Zubair

If the setting “queue conflicting jobs” is not set which schedule will start? Full, Incr or random ?

It’s seems a random behaviour

It would be random - survival of the fastest thread. There is no logic to handle conflicting schedules to be able to pick the right one to run.
