Applied online through Northwell Health jobboard.
Reached out to by a 3rd party talent manager who handled all communication and scheduling between myself and the actual company. Had 3 interviews - 2 at the New Hyde Park location and 1 at the Upper East Side location (though this was due to the fact I was passed for the position I initialed applied for and was passed to another team in need of a support associate). Overall, these interviews were quite easy and causal, mostly just there for the current employees to get a vibe from me to see if I would fit with them. Only "task" required was a review of an acknowledgment letter during my first interview to demonstrating my editing abilities (spelling, grammar, syntax, etc.)
