Thornhill was very capable and willing to customise any area of the online selection tool for our programme … They were also very willing to make any adjustments and no technical issue seemed too complex for them to handle.  Thornhill was a great partner to ensure total customisation for our client … The team was always available and willing to help – even after hours and weekends.  Their response time was swift and the work done was extremely accurate. We had a very tight deadline to complete this project, and Thornhill made sure we were able to do it in time.  So in terms of speed, responsiveness, reliability and quality: YES, YES, YES and YES, without a doubt. I would most definitely recommend the Thornhill team.
