SHO job interview

Hi there,

I applied to HSE for a 6 month SHO job in Ireland and have an interview this week. Can anybody tell me about the kind of questions they actually target in the interview??
I am sure there will be something related to Medical knowledge as well. Guys what do u think i should prepare?
Also, i am not able to be in person in Ireland for my Interview because i was notified late and the embassy takes about 8 weeks to issue a visa. That's sick anyway. Will this affect my Interview?

Thanks for your help in Advance.
