As HMRC applications are Behaviour and Strength based it is good to ensure you articulate your successes relevant to the job being applied for. Ensure you follow the STAR (Situation , Task, Action and Result) format. with your achievements think What was the Situation, What Task needed to be done to resolve / improve that situation , What actions did YOU do to achieve a result and exactly what was the result in you taking those actions. Always think in terms of what YOU did. Highlight yourself with actual examples.

Keep your mind and eyes open as there are are so many opportunities

One thing I've found since being in HMRC is that there is a real motivation for the workforce to reflect the diverse society that we serve. The success profiles often used in recruitment can seem daunting, but actually they allow everyone no matter what kind of previous experience we have, to demonstrate those transferable skills, or behaviours, which can be drawn upon, with the right training, to be successful in a brand new role. So don't let anything make you think you don't have what HMRC need or want, whether that be challenging personal circumstances, health difficulties, or lack of prior experience, the Civil Service is here to support everyone in our society, and so it should be made up of a diverse workforce that can accurately represent everyone.
