Regardless of your previous experience you would be put in the same "box" as the pay 2 fly, zero to hero, guys and asked to pay a rating and work for "free" for the first god knows how many years. Don't do it.
Have you ever worked 850 - 900 hours per year with an average of 3+ sectors per working day? Done 4-5 consecutive early check-in, 10-12 hour days, 10 days per month? Don't do it.
What type are you on at the moment?
