My code + fix by switching to another zip library (node-stream-zip)
https://github.com/sreenaths/mock-ats/pull/4/files

  zipFiles.upload.forEach(function (file){
    var unzipDir = file.path + "_dir/";

    fs.createReadStream(file.path).
    pipe(unzip.Extract({ path: unzipDir }).
      on('close', function() {
        fs.readdir(unzipDir, function(err, files){
          if (err) throw err;
          files.forEach(function(file){
              var json = JSON.parse(fs.readFileSync(unzipDir + file, 'utf8'));
              extractData(data, json);
          });

          completeCount++;

          if(completeCount == zipFiles.upload.length) {
            callback(data);
          }
        });
      })
    );

extra close event is triggered with files being [] for the first event and correctly populated for the second close event.
