To set up an approval process ahead of time that specifies a strict sequence of approvers, create a sequential approval chain.
In sequential chains, each approver in the sequence will receive a request to approve only when the previous approver has approved the job or offer. All approvers must approve in sequence, or the job or offer cannot be published or extended.
In this example, James Hetfjeld will receive the first approval request. When he approves, the hiring manager on the job will receive an approval request.
