This is how far I have gotten in obtaining my Z Visa and the time frames:
Here is the experience I have gone though so far as of 15 August 2014

July 15 I received and signed the work contract.
July 16 I received a link to take an exam: evaluation.safea.gov.cn/login.php (I took the exam and the next day I received my total score of 80.4%)
July 17 I took screen shots of the exam and sent in my score along with my passport, resume, degrees, letter of reference, and certificates. The employer also asked me for multiple certificates and letters of appreciation from different companies so I included those.
August 10th I was informed that I was approved for the work permit but will have to still wait for the Invitation letter.
August 15 2014 I received an E-Mail with the work permit issued by the State Administration of Foreign Experts Affairs P.R.C. and then I was informed that the employer is still waiting on the Chinese Government to issue the letter of invitation. They said it needs to go through 4 different government offices to get approved and that I should expect its approval on 19 August. (I will let you know if this will happen).

I was told that the Chinese Consulate in Houston TX may take 2 to 3 days to process the Z Visa.
