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!

I really believe that if you work hard and give your very best in your career path then you will succeed in the role you want to get to. I took every opportunity in my career to develop my skills and learn new skills which helped me to progress in my career.
