As has been pointed out ones ATPL theory exam results are often used as a filter to get you the interview. But then you must too be prepared to answer technical questions should you be invited to interview. Most operators will know that question banks are heavily relied upon to help pass the subjects and as such may not ask about your exam results directly but possibly ask some ATPL theory questions to test your real understanding and knowledge.
Hammering the question bank is no way to properly learn the subject rather more to help one understand how the CAA is wording and asking the questions. Some questions are worded so ambiguously or even poorly translated from other EASA member states, that it is almost impossible to understand what they are asking! Learn the subject content properly before attempting the question banks and use the banks to test your knowledge not to memorise the answers.
