Did they send you an email with interview questions after your online application? Or before you had your dmi?
No. If I remember correctly, the process went pretty much as follows:
1) Completion of online application form along with attachment of CV
2) E-mail inviting me to interview once venue for interview confirmed
3) Attended interview where the usual sort of questions were asked
4) Telephone call a few days later advising interview was successful and a job offer was pending subject to passing a medical
5) E-mail confirming medical appointment received
6) Attended and passed medical
7) Await start date (still waiting over two years later)!
