Unless you have a job offer, a TR with no hours is not going to help you and will potentially hurt you. Please don't make the mistake of thinking that type-rating=competency, it does not. There's a reason most airlines don't take cadets! Trust me, when you get your first type rating you will know next to nothing about the aircraft, the bare minimum. It will take 1000 hours just to start getting comfortable. If you turn up to an assessment with a TR and no experience you are going to really struggle. If you are non type rated you will generally have an basic assessment to include some manual handling and maybe an ILS: you will be compared to your peers. If you are type rated they will expect a far higher level of competency (think engine failures etc), and you will be compared to people with 1000s of hours in the aircraft.
