Ok first day back in the office and filtering through some of these threads...
As soon as you turn down an offer you are placed back on the merit list. However if you reject an offer to add an occupation to your file you will be moved further back in the proces. There is an MPAC happening in February. However not all MP applicants are doing the MPAC, depending on where you live the new "Interview" only method is still being used. If you choose to to reject your offer and apply for MP, your file will be moved back in the process until you complete the MPAC/MP Specific Interview (this is a secondary process to the MCC Interview).
Q. Lamb each occupation can be different and there is more involved in the background recruiting process than simply having a medical and CFAT; even if someone has previously interviewed for an occupation and removed it from their file, if they decide to add it back another MCC Interview maybe required; or in this case further testing. As an applicant you should avoid giving application advise to other applicant's unless of course it's your personal experience, then you should state "in my personal experience..." I don't want to come off as sounding harsh but as someone who works in recruiting I get queries all the time of "someone told me..." and the information is incorrect.
Thanks for the vote of confidence
Some CFRC's are operational again as of today; others are still on holidays until 15 January 2018. Please be patient with Recruiters & File Managers while they get caught up in their workload.
