In the UK, every job is given after interviewing you, this is a formal event. Your CV gets you the interview, the interview gets the job. Typically after shortlisting you, the hospital will ask for your referees opinion about you and your capabilities. So once shortlisted, do check with your friendly referees if they have been asked for their reference or in short warn them to wait for one such letter. Sometimes the referee may know some one in that hospital and he may want to ring him about you and put in a good word.
You have to be formally dressed for the interview which means jacket, trousers and tie and leather shoes. Look clean, smell nice (so get the jackets from out of the cupboards and air them. Curry smell can stay deep!) and practice your mock interview.
The first step is to show interest so do ring the hospital and ask them instructions about reaching the hospital. Try and reach there the day before and have a look around. It matters a lot to consultants that you took that extra effort to know the hospital. Medical staffing will try to put you off saying, there is no accommodation the night before etc but you need to persist. More on will be on the YBCC soon.
Find out who is interviewing you, that is not a secret. Do find out a bit more about that person, his interests, his latest success, pet project and what not. If this cannot be through the internet, ask his registrar when you reach that hospital.
The interview typically starts with "what have you done so far in your career" which is basically running them through your CV quickly. Don't linger on silly things such as "I was in a convent school" that makes sense when you are not in front of me, now your English will speak for itself!
Some typical questions are "why have you come to the UK?", "tell me about an interesting article you have recently read", what is the difference in medicine in UK and that in your country", "what are your long term plans". Often they ask silly sounding questions such as "tell me your good qualities" or "tell me your weaknesses". You cannot sound too boastful and tell them about your good looks or incredible medical knowledge. Neither can you be too honest and confess about your love for things spiritual (especially distilled and bottled) whilst answering the second question.
