Though those that have already answered this question are technically accurate in that you can seek upgrade once hitting 1500 hrs and/or if you have enough hours you can apply for DEC, it’s my opinion your flying background and particular experience should and likely does play into the situation.

I had hopes of a quick upgrade path, however, after getting in the door I’ve heard from a couple of sources the company ‘prefers’ you get experience flying the summer and winter season as an SIC before upgrading you to PIC; considering the various WX challenges associated with those particular seasons. As it could be argued the typical guidance from the light plane GA playbook is to stay on the ground, and/or wait another day, etc., if that type of flying is what your experience is composed of, flying those 2 seasons as SIC is a good idea, IMO. If however, you have amassed real world experience across the seasons as an FO of a similar type of operation in a similarly equipped and capable aircraft, then I think it’s realistic to think you could come in as DEC or quickly upgrade.

All this said, the other advantage of taking your time is the ability to learn the ropes. Flying the plane is easy, it’s the FMS and Flight Director/AP that will throw you curveballs. Though training is very good, fire hose syndrome limits how much can realistically be thrown at us and the reality is, time/real experience is our friend.

Additionally, there’s a customer service and business aspect to the job as well. It’s been beneficial to see how an experienced captain handles various situations, both corporate and customer. What I mean by corporate is, the flight operations center schedules us to do X, it’s been beneficial to see an experienced captain push back on certain requests, where as a newbie might be apt to just accept and roll with it, it’s nice to get a sense of boundaries - and I’m not talking about whether we fly or not fly.

Though I was hopeful for a quick upgrade for financial reasons, the reality is, I’m thoroughly enjoying the role of FO and having the time to learn the ropes properly. I’ve flown with some really great captains that took an interest in expanding my knowledge base. Are there long days, yup, do you get tired at times, sure do, but it’s been a blast so far; for me personally, the type of flying we do and the job is exactly what I hoped it would be! Your mileage may vary!
