That sounds better than an interview, but a written test is not representative of many types of work. In most kinds of work you'd have days to work on a topic, access to reference materials, the ability to discuss with colleagues and ask for help, etc. Test results probably do correlate with job performance, and it may be better than an interview (not sure) but it's say it's still quite a long way from giving an accurate answer.
