The interview process consists of two steps. The initial and the final interview. Initial interview is very easy as they will just ask you basic interview questions such as "Tell me about yourself, why do we hire you? How do you see yourself 5 years from now, etc." Upon passing the initial interview, you still have to take preliminary exams before you get to the final interview. The final interview will be done by the account supervisor or someone higher in rank. You must portray that you are confident and eager to get the job in order to convince the interview conductor that you are fit to the position they are looking for.
