I have been working at King Kong part-time (Less than a year)
Best working atmosphere till date. You can work with peaceful mind. The all peaceful minds leads you to positive response and which leads to great progression to the company.
There is no negatives i can think of.
The process took 2 weeks. I interviewed at King Kong (London, England (UK)).
Fired in an application that included an extensive cover letter. No reply or response for 2 weeks made several calls to follow up. Nobody ever there to take the call. Promised several call back but none materialised. Unfortunate. If there was no interest a little courtesy to say would have gone further. Going by research and advice from other places it seems this is a high turn over of staff agency. I would advice to avoud unless you're desperate or looking for something for short term.
