From an HR perspective, recruitment is a process. However, the situation of the interview will basically be finalized after the interview. All that is left is to follow the process and see if there will be any problems in the process. At this time, if the leader wants it, give him a verbal offer to stabilize you. If it is the leader's choice or not, you will be asked to wait, because people may not accept the offer, so you still have to prepare spare tires.
As an applicant, as long as the offer does not arrive, continue to look for a job and do not wait.
