New job help

[yetanotherweasley]

Name changed for this as potentially outing.
I was lucky enough to have a successful interview for a job which is a big step up for me. To be honest I'm not sure how I got it but I did and I'm very grateful. I'm going from basically a bottom feeder to management. I know the company and I understand the job but I'm a bit worried.
I have experience managing people but the job description vs the actual job are two very different things. I'm facing hiring and managing over 20 new starters to a role I have no knowledge off and am expected to do this within my first 3 weeks.
I'm also expected to implement a whole new process into a place of work which has never had a department like this before.
I'm worried, has anyone got any tips for me. I was so excited but this is miles away from what was written on the description.
Also has anyone got any diary recommendations. I've been told it's going to be very very full on and having lots of meetings, appointments etc as well as now having to do an additional role on top so am going to need to be very organised.
Any help would be great.

Hopeful bump

I once applied for a part time job when I was at uni.. had no idea what I was supposed to do and never really understood the meaning of the technical terms used (property field) I just went with the flow.. worked there for two years and at every meeting - apparantly because of my hard work and being 3 months ahead of schedule we kept getting bonuses. I still have no idea how tha worked out.. :)

Firstly, congratulations! If you know the company and what it entails you are already half way there and the above means you have no bar set to fail, you need to fake it till you make it!

People management is no different to childcare or dealing with family life, well it is but you get where I’m coming from.

Firstly find your feet and work out who is who in the management team to find yourself some friendly faces and people you can confidentially bounce off of. It’s a new team so involve other dept heads in your ideas to make it work and take on their feedback

No one hires with the hope that person fails, it looks bad on them more than it does the departing probation failure. Try and think about what you did to be offered the role and feed off of that for the first few weeks.

Enjoy your new adventure, you were hired for a reason!
