It is important to keep trying. Not everybody will make it first time, I did not when applying for Tax Professional Training, but I was put on a reserve list and called up later. Many do not make it first time but they do make it second time round. The process for recruitment can be long, but do not get disheartened, this is to give everybody the best chance of being accepted. If you can, get feedback and consider it for future applications. Feedback will often point our your weak area that can easily be improved with a bit of practice. If you do get on a training programme, be aware that though tough, they want you to succeed and will do everything they can to support you in achieving the end goal. Do say if you need extra support, they cannot provide it unless you tell them you need it. I am dyslexic and they took this into account for exams providing computer rather than writing and also extra time for reading.

I've had a huge variety of roles in HMRC, and I've enjoyed all of them. I've found it's not always necessary to chase promotion. A sideways move to another area can expand your horizons and build your skills and this is recognised when you're ready to take the next step. I've always tried to maintain job satisfaction above all else. I've done a couple of jobs I've really hated, so I moved on and found something else. I've found if I'm happy in my job, I perform better and this is noticed. Also, don't be afraid to ask for opportunities or for what you want. I've always believed 'if you don't ask, you don't get' – the worst that could happen is someone says no and you're no worse off.

I have been very lucky in that I have almost always been given a role (or applied for one) that I have enjoyed in HMRC (or earlier departments). If you show that you are keen to learn and willing to listen, then you will find that opportunities will present themselves to you and you will progress in your career. When I was told that I would have to undertake taxes training in 2005, I was horrified. Having been trained in National Insurance and done various management roles, I thought that tax would be just too hard for me and that I wouldn't pass the exams. However, I committed wholeheartedly to the training programme. I studied hard and passed all the exams first time - even though my daughter was still a baby so I was constantly exhausted as well as having to travel to London once a week for 18 months for my tutorials!
