I can only recommend interaction with someone who is well versed in dealing with interviews. Coaching is needed on a one on one basis in order to perfect her interview style. This need not be an aviation professional, merely someone who's speak is motivational. There has to be some form of explanation as to why she struggled with the ground school if so asked. Your daughter needs to provide a draft of all potential interview questions and be prepared to be put through mock interviews. I am sure that you could help with this scenario? This should be taken seriously as it will equip her with a skill set to deal with any question posed at interview. Always respond with positivity. As said above the interview is the place to overturn any negatives and always put a positive spin on any question that is thrown at you. If your daughter displays undesirable non technical skills (you say that she is shy) this will not be received well at interview. It could be seen as telling that she has already had a couple of interviews without success, in reality this is something to be concerned about considering the big financial and personal commitment invested already. Every pilot from cadet to captain must prepare in detail when going for a job. We have a saying in aviation that Prior Preparation Prevents P*ss Poor Performance.
