Stobelma is right.
Any (okay,
most) Commercially-qualified candidates can be trained to fly an RJ. Between the rampant Automation (after all, a monkey can fly just like you!), your company SOP, the somewhat-experienced Captain sitting beside you, and FAA 121 Reg's, it takes real talent to bend metal, or worse, hurt a passenger.
This is not a question of whether a job is being offered to you pre-graduation. It isn't even a question about whether you're safe in the Aircraft. Bottom line is that if you are offered the job, and you can honestly say that you are ready to commit the time and effort to passing training, then yes, you'd be a moron to turn it down. What we are talking about here are real-world life and aviation-skills. Take it from somebody who was flying a Jet at 400 hours...I had one helluva steep learning curve - things that they
can't teach you in a Simulator. Any flying experience beyond those coveted 250 hours are going to make you a more well-rounded Pilot and person, and thus a greater asset in the right seat of a Jet. Something else to think about...sure your ego may be thrilled to be in a Jet at such low-time, but only shortly...that same ego, as well as your pride, are going to take an incredible beating when you can't fly the plane for beans. If you're going into a 450kt machine, you'd better be able to walk the walk.
The industry has changed. Don't expect that job-offer tomorrow. Remember, it is not so much about
where you get, but
how you get there. Just do it in style, my friend.
