All good airlines want their new-hire pilots to achieve ICAO level 5 or 6. If you are applying for an airline as a cadet pilot and only have ICAO level 4 you will probably be advised to keep working on your English throughout the selection process. One of the big mistakes we see is that weak candidates stop learning English after they reach a marginal ICAO level 4. But what happens to these candidates after they begin their cadetship? Some find flight training difficult, others fail check-rides and get grounded when back in HK, and one even had a tail strike because she misunderstood directions from an instructor.
So keep improving your English, even after you pass. You will inspire others and enhance the safety culture of your airline.
This is the best course to help you improve your English if you have less than 250 flying hours. http://aviationenglish.com/english-for-pilots-and-atcos/icao-aviation-english-for-cadet-entry-pilots
