Reply to Getting Music Signed to a label & the process behind it

Hello its been a while since I posted anything on here but I just had some stuff I wanted to ask other producers that have been signed with labels. Since I'm totally new to the concept. My story is that a digital record label messaged me online asking to sign a track I posted.

My questions are:
1. What is the process of getting signed? (the whole process from now till the track being on a digital record site.)
2. How to deal with them as in conversation wise.
3. Since I live in Toronto and the label is based in New York is there any way to make sure this isn't some kind of scam or something funny...

Sorry if its a stupid question I'm just kinda weary since I dont meet the guy who wants to sign my track face to face especially since its my first time. Anyone who can shed some light on the subject is appreciated! Thanks a ton.
