From the initial email...
Thank you for completing your online application form.
We would like to confirm that we have received your application for First Officer.
***Current Vacancies***
All applications for current vacancies will be screened to ensure they meet the requirements for the job.
Following the initial screening, the most suitable candidates will be invited to participate in the next stage of the recruitment process. If your application is successful at this stage, we will contact you within 4 weeks of the vacancy closing date.
If you have not heard from us within this time then we regret to inform you that you have been unsuccessful on this occasion. We are unable to provide individual feedback as to why your application has not been successful due to the volume of candidates applying to our vacancies.
All correspondence will be through e-mail and we strongly advise you to monitor your e-mail account.
So by that I assume if you have heard nothing by 8th August (+ 4 weeks) it's game over.
