It will probably also come down to your age and location whether having any flying is beneficial or not.
If you are out of uni and live outside of Hong Kong say Canada, USA or Australia, then there shouldn't be any reason why you haven't atleast done a few lessons. Even if you are still at uni, having some flights under your belt wouldn't be too much of an expectation.
Don't get lessons for the sake of trying to improve your interview chances. Do it because that's what you trully want to do.
Question to ask yourself is, if I fail, am I going to say "well i tried" or "I love flying and this is what I want to do with the rest of my life, I am going to get all the licenses regardless of the outcome".
If the latter is your choice, then take up flying lessons. If it isn't, you probably need to think about another career.
