Hi,
I have just one question: could I have more possibilities if I got a PPL with at least 120 hours?
It may help you, but I don't think it will harm you. During my interviews, they did ask me if I am so interested in flying, why did I never get my PPL. The interviewer told me to look into getting a PPL first if I was to reapply.
Also, the recruitment lady stressed to keep them updated with your hours, so I believe that it can be a factor to get you in.
In the end, it all comes down to how they think about you during the interviews. If you have 0 hours and will be able to persuade them that you love flying, then the PPL is probably not necessary. But the PPL can help to show your interests.
