Check the "trainedClassifiers/Employer" and "trainedClassifiers/Candidate" folders. Each should contain a new file - MostRecentClassifier.json - that contains the trained classifier.

These folders MAY also contain another file - RetrainedClassifier.json - from a previous run of the server. If this file exists, it takes precedence over the MostRecentClassifier.json . If you want to use your MostRecentClassifier, delete the RetrainedClassifier.
