You need to believe in yourself and take any development opportunity offered to you. Training and learning is important and is encouraged so you can do your job effectively and develop skills that can help you throughout your career. Constant development is important for you, your team and the wider business. If you are interested in pursuing something - consult with your manager to see if they can help identify opportunities or courses you can attend. Not all courses are internal and in some instances the department will pay to attend external courses or attain professional qualifications. There are also great training and development schemes that exist in HMRC

When I moved from Pakistan, I was told by many that the only jobs I can get is working in a shop as graduate careers aren't for us. The fact that I didn't take their word made such a difference. Self-belief is the first part of the equation and once you have that, top it up with doing your research and acting on it as actions make the most difference. There is a lot of material available for applications and what it takes to be a civil servant at HMRC. Have some time to read and understand it before applying. Lastly, overthinking is not your friend, so my advice is to do your thinking but DO NOT over think and take actions to make a plunge!

There are a huge number of roles within HMRC and the wider Civil Service. There will be some that really suit your skills. Where there is a gap, the training and development opportunities available will give you every chance to fill that gap and find that role where you can excel. You will find management want you to improve and will encourage your development, whether within your current role or to achieve the abilities to change to somewhere else you can be better. Self-belief used properly can be your strongest skill.
