We have find the issues for this ticket, it's regarding the 401 error while creating the zoom-meeting-link.

I'm thinking if that we could re-send another email to the candidate and allow him to re-process the steps ?

[LieutenantRoger]

This should be an enhancement

Problem:

Currently, once the candidate failed to schedule an interview, e.g. returning 401 while creating a zoom meeting link, then he is no longer able to re-schedule the interview. And he will not know that his last scheduling interview is failed. At this time, the interview flow is broken due to the system problem.

Solution:

After our discussion with Sachin and Sathya, we concluded that, we will need add below enhancement logic

1. When it's scheduling interview, and when creating a zoom meeting link is failed with 401, we will retry a configurable times (default to 5), then continue. If after 5 times, we still are not succeeded in creating a zoom meeting link, we will
2. Stop continuing the current scheduling process so the interview status keep as 'Scheduling', then afterwards
3. We will send another interview scheduling fail email to the job candidate, so that the candidate will get notified about it, and have another chance to re-schedule the interview.

Conclusion:

We believe doing so that will wire up the flow as a complete.
