Gofynnodd Anhysbys gwestiwn i Daniel S.
Thank you for the questions -
1) In my experience, the managers were very aware that 'we' (external to HMRC) were entering the organisation with no experience and as trainees. I never felt as though the workload was ' a lot' - as I came from Teaching/recently completing a teaching degree, which I'd be spending most of my time at weekends marking and lesson planning.
In contrast, at HMRC, my work could all be done in the contractual time. I never spent time outside of my working hours, unless it was for additional study nearer an exam.
As trainees, there is support available to manage the workload and your time is yours to organise - if you're proactive and organised, the workload, in my experience, was never a problem. Generally, when I joined, the workload gradually increased. I started with training, given 'project' work (unrelated to HMRC - to settle into the team/working with others in your cohort), followed by case study work, then given 'live' case work. The programme was organised in a way that a typical week for me would be 1 day of tutorial, 1 day of self study, 3 days of office work. This was enough time to complete the work given to me, as well as having time to find my own 'opportunity' work.
2) I joined without any experience of working with numbers in a tax scenario. As long as you can pass the numeracy tests and get onto the course, working with numbers shouldn't be an issue. In my day to day work, I rely more on reading and interpreting legislation instead of work with numbers/complex calculations.
Hope this helps/answers your questions. Let me know if you have any other questions. :)

Mae’r wefan hon yn defnyddio cwcis.
Rydym yn defnyddio cwcis i bersonoli cynnwys fel argymhellion swyddi, ac i ddadansoddi ein traffig. Rydych yn cydsynio i’n cwcis os ydych yn clicio "Rwy’n Derbyn". Os byddwch yn clicio ar "Nid wyf yn derbyn", yna ni fyddwn yn defnyddio cwcis ond efallai y bydd gennych brofiad defnyddiwr dirywio. Gallwch newid eich gosodiadau trwy glicio ar y cysylltiad Gosodiadau ar frig y ddyfais
Mae’r cwcis hyn yn angenrheidiol er mwyn i’r wefan weithredu ac ni ellir eu diffodd yn ein systemau. Fel arfer, dim ond mewn ymateb i gamau a wnaed gennych sy’n gyfystyr â chais am wasanaethau, megis gosod eich dewisiadau preifatrwydd, mewngofnodi neu lenwi ffurflenni. Gallwch osod eich porwr i’ch rhwystro neu eich rhybuddio am y cwcis hyn, ond ni fydd rhai rhannau o’r wefan yn gweithio wedyn.
Mae’r cwcis hyn yn ein galluogi i gyfrif ymweliadau a ffynonellau traffig fel y gallwn fesur a gwella perfformiad ein gwefan. Maen nhw’n ein helpu ni i wybod pa dudalennau sydd fwyaf a lleiaf poblogaidd a gweld sut mae ymwelwyr yn symud o gwmpas y wefan. Os na fyddwch yn caniatáu’r cwcis hyn, ni fyddwn yn gwybod pryd rydych wedi ymweld â’n gwefan, ac ni fyddwn yn gallu monitro ei berfformiad.
