In my humble opinion from past experience:
PIC time in an aircraft that is similar to what the company flies, is valuable, as is SIC time in that same aircraft.
Depending on the airline, the quality of time is equally important to the seat you occupy.
Having said that, TPIC will always be a plus in getting the call. Even though, there are thousands of RJ captains with 1000 TPIC.
In some cases having TPIC might hurt you, just like having too much time.
I know many competent and experienced pilots who are not getting calls. They are considered overqualified, and high risk.
No one really knows what each airline is looking for. Even if we knew, the standards change constantly.
The greatest challenge for many is, to enjoy the job while trying to get hired.
After all, flying is fun, or we would not do it, right?
