It means we should not change tha native vlan from 1 to any other, vlan 1 should be always for the network management purpose.
One more thing which is asked bye interviewer to me that why do we not need to configure STP if our managent vlan is already 1? Is this related to the last topic?

It's all about what do you want to do. In most cases I can't think of a good reason to have this kind of inconsistency in a production network. The network I currently administer was setup with some weirdness like this before I arrived. I discovered some of the "Bad Things" mentioned earlier where they actually had traffic bleeding between VLANS that they thought were isolated. It is actually best practice to make the native VLAN an unused VLAN, and make sure all production VLANS are tagged.
