I don't think anyone can really answer this question! There was a rumour that they only were hiring a specific number from Scandinavia at my assesment day so when i had my personal interview I asked about it. She just laughed and said that they took whoever they see fit for the job. So theres no general ratio, if u're what theyre looking 4 they'll hire u.
All u can do is wait... Which really sux! But good luck anyways!
