I got a phone call asking me to start the next day, the recruitments process is the least stressful thing about the job
I didn't necessarily have an interview it was more of a conversation as to when I could start, most people were employed on a first come first served basis not on their experience
Easy, they ask you a few questions and thats it, dress smart.
Relaxed. Be confident in yourself.
I was nervous but the process was easy and they made you feel comfortable at all times.
