Thanks for your question.
Firstly, the good news is that your resume is obviously working! This means that you are selling yourself effectively on paper at least.
All you require is some coaching to transfer this into selling yourself in person.
A starting point for effective interview skills is to realise that the fundamental skill involved is not knowing the best way to answer questions but rather it is public speaking.
Many people struggle to sell themselves effectively in interviews simply because they have a fear of public speaking. There are simple solutions to this issue.
Next is to realise that one of the patterns that leads to poor interviews is projecting your mind forward and imagining you won't know how to answer a question. The usual cycle is to imagine yourself completely muddling up the answer and feeling really stupid.
The way many people deal with this is that they avoid adequately preparing for the interview as that way they avoid this little hullucinatory and painful cycle of thought.
This is not a helpful pattern to go through as it usually becomes reality.
Selling yourself effectively involves knowing the product inside and out! That requires complete due diligence in preparing for the interview.
If you have any doubts about your ability to interview effectively - these need to be examined to identify the underlying cause.
The good news is that once you deal with these issues they stop hampering your career development.
