I did all my flying part 61. Was a CFI for a year. I actually enjoyed that. Then landed a job at a regional. Upgraded in three years. Spent the next ten years as a Captain. Should have put out resumes, and with any luck, would have been at a Major by now. So, pick the right airline at the right time and you will upgrade quickly. Maybe make it to the next level in a year after that upgrade. If not, it might not turn out so rosy. I have sat next to talented pilots that have been in the right seat of an RJ for nine years. That's not to say you will not get hired without PIC. It does happen, and quite often now. You hopefully have one thing going for you. The next ten years should be much better in this industry.
