iSoftStone Search Engine Evaluation interview questions

no interview, only testing, two separate tests,,,, two attempts at each to pass,, rather simple mostly,, but the odd harder questions,,,, no need to add more,, I no longer work for this company

I submitted an application and received an email a couple days later requesting that I complete the practice/training and the test evaluation for the position. I passed the test after hours of reading through their guidelines and completed the practice and exam. I was offered the position, signed the contract/provided personal information and then heard nothing from my point of contact. I emailed my point of contact multiple times to follow up and have received no response. I reached out on their website to see why after signing the contract, I haven't heard anything additional about starting the position that was offered to me and still nothing over a month ago. In my opinion, this is extremely unprofessional and I would be wary to work for a company that conducts business this way.
