I do not know what is being explained to this young individual but for all intents and purposes he needs to ensure that the courses/curriculum he is taking or is going to take is based on the work that he hopes to be able to perform. He/she should be diligent on ensuring that the positions he is striving to obtain are met by the training he/she has completed. Get the pre-requisite training before applying for the position posted. If an interview is granted go there looking neat and professional. The interview is the process that makes or breaks the opportunity given. Answer the questions asked honestly, don't try to bull_ _ _ t the interviewer, because it does not work. Impress them with credentials that meet the demand. If nothing else the experience will be the eye opener for the next one if you are not successful on the first one. ANSWER THE QUESTIONS ASKED, don't elaborate, simple and quick. Take a second to think about the approach to answering the question, then answer it. If you don't know, say you don't know. If you are unsure, state that you don't know. Better to be honest about your knowledge level rather than make a fool. These suggestions of course are only mine and should not be interpreted as being solemn. I have performed many interviews and of course have been through many, and this is only my advice. All interviews are different and all interviewers are different, some very precise, some very professional, some just want to impress the interviewee. This becomes very obvious, very quickly. My advice is to maintain your posture and don't let a bad interviewer ruin your day, but be professional regardless.
