I have been with this agency for 8 months and they have found me a total of 2 days work. They are very good at making you think they are looking for you. On several occasions they called me to ask if I was interested in a position, I always answered 'yes', and the end of the conversation they always say that the position has been filled. This has happened many times with Quantum and I've yet to meet anyone who has had a different experience.
The reason I have given them 2 stars is because the consultant who calls me, to raise my hopes then disappoint me, does it very pleasantly.
