The IKM test uses a 10-point global percentile scale, not a percentage correct. You are compared to a norm group of developers who have taken the same test.
The most significant shift in the updated IKM Java 8 test is its heavy emphasis on . Java 8’s introduction of lambda expressions, method references, and functional interfaces (like Predicate , Function , and Consumer ) fundamentally changed how developers write Java code. The IKM test does not merely ask candidates to identify a lambda syntax; it presents complex scenarios involving variable capture, effectively final variables, and the behavioral differences between anonymous inner classes and lambdas. Furthermore, the test probes the java.util.function package in depth, requiring the test-taker to understand when to use BiFunction over BinaryOperator or why IntSupplier differs from Supplier<Integer> . A candidate who learned Java 8 superficially by "replacing anonymous classes with ->" will find these questions particularly challenging. ikm java 8 test updated
