Hi, I did a negotiation for my
NRF AC last year and I was so scared as I hadn't done one before and had no idea how to prepare.
What is helpful is glossing over terms you may see in a contract as you are most likely going to be negotiating terms of a contract for a client. e.g warranties, indemnities, shareholders, lock up period.
I usually love to debate, but I was intimidated during my actual negotiation because we were in teams and I was the only girl and everyone was older and I don't know why but that spooked me. I ended up not speaking as much as I had hoped. However, because I feel like I contributed quite a lot during the preparation time (which you most likely will have with an observer), I think that's what helped secure me the scheme.
What I realised is, of course you want to negotiate the best terms for your 'client', but you also want to make sure you conclude the whole thing before the time runs out. Otherwise your 'client' gets nothing.
A good way to secure extra brownie points is to either be a timekeeper, or be the person that helps provide 'structure' (if you're in a team) e.g being like hi I'll take clause 1 and 2 and you can do clause 3 and 4.
Good luck! Hope this was somewhat helpful
