Is this a linkedin/whatsapp scam?

I dont really know how whatsapp works, i only have it because a past job used it for a work groupchat. Is it possible to search up people's numbers? I have no idea how this person apparently got my number from linked in as its not on my profile there, part of me is wondering if they maybe meant indeed? Idk something just doesnt feel right about it. Even if its real im not interested in working for an american company as a canadian right now. What puzzles me is how insistant this person has been since day one.

I will mention that my name is in my government's "job bank" so my information is a little extra public rn, im working on removing myself from there because i constantly get texts from random numbers with just "hi" or "hey can we talk?". I know this is because of the job bank because ive asked one of these random ppl where the hell they got my number and info.
