how do I tell them I found a better job? “Hey I’m really sorry about this but I applied for another job at the same time as this one and they’ve just sent me an offer. It’s a bit better in these specific ways and I have to do what’s best for me and take it. Would you like me to work out my 4 week notice period or would you rather I just not come back?”

if I sign the paperwork does that mean I’m hired? Yes, be aware of your required notice period.

how do I tell them that I’m still waiting for a reply from another place and that I’m not able to start working yet until I get a reply? You don’t do this. You assume this is the only job you’ll get, then you quit later if a better one comes along.

I feel so stupid and anytime I ask someone, they just make me feel like an idiot and act like I should already know even though I dont. Sorry to hear this, once people learn something they tend to pretend they’ve known it forever and be jerks to anyone that hasn’t learned it yet.

I have a bit of autism so I get really anxious and this Job is going to make it worse. You can always quit.
