Try different areas. Don't stick to one

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!

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.
