100% yes! The skill of interviewing well is one that can be learnt and can be taught. If you have the ability to practice and learn from others, you will absolutely be able to do well. Confidence is something that comes with practice and time, and as such has nothing to do with natural disposition. If you are already at interview stage, you are a competent and competitive interviewee, and so you need to trust yourself - you have every right to be there. Practise is the single most effective thing to increase confidence and your ability to do well at interview, and as such we would recommend interview tutoring as a good way to achieve this.
