It can be a very daunting experience starting work for a new employer, no matter what your age or experience. On my first day in the office (having never worked in an office before) I dressed in full suit and tie, only to find my colleagues were in smart casual dress. This was 33 years ago and now a simple question could be asked on a platform such as this. Then there are the ways things can sometimes be explained incorrectly, it's not anyone's fault. Generally no one is specifically trained in dealing with the diverse nature that working/office life can bring. Rest assured HMRC is a great place to work and One of HMRC's Values is that we are innovative, We are committed to continuous improvement and to developing ourselves. Another is that we are professional, We partner with others and collaborate within and across teams to achieve great results.

Once established the keep your options open. The department and Civil Service are vast, work is varied and options are unlimited. Look for opportunities to expand your knowledge, experience and contacts.

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!
