I have been dealing with Excel HR for 5 years. So far I secured 3 positions through them. Here is my review of them:
Pros:
1) They know how to set their rate to win positions, which gives people who register with them a higher chance of getting a job
2) All their agents were polite with me and professional. They answered their phone and email on time and provided me with the necessary assistance.

Cons:
1) They are very greedy and cheap. It is good that they set their rate lower than other agencies to win the contract. However, once they win the contract, they take at least one third of the worker's salary for themselves.
The fact that they helped me find a job is great. However, when my contract got renewed a few times, it is because of my personal effort and because I was a good worker. They did not make any effort for my contract to be renewed. Therefore, they should not continue to take the same rate out of my pay check after my contract is renewed but rather they should leave me with a higher salary.
2) Every time my contract was renewed through them, I asked for an increase in salary but they refused.
3) I know people who were interviewed by them and have been waiting for months but never received an offer through them.
