Fellas,
To get into the pool, you only have to pass to the min standard required. Once in the pool, some may be more equal than others ie: might have more hours, have scored better etc. Being in the Pool is not a job offer.
Things changed this year with the reintroduction of DECs. This almost halved the number of FOs required. Once your 12 months in the pool is up, you need to re-interview etc. This has also happened in the past. To be eligible to be asked back to interview you need to fulfill the selection requirements, and also be competitive against those also waiting. This great for the company, but may not be so good if you are now unemployed etc. Good news for those that were in the pool is that the extra hours gained in the past 12 months will help your application.
