Worst reference providers ever, using outdated methodologies that are not fit to modern reality and asking your colleagues to breach GDPR requirements. I was very dissapointed by the experience with them and after my move from Hong Kong, where such providers are always to try to find the smart solution. Their processes are not adapted to work with work from home environment of your referents, neither they are adapted to big companies reality. For one week they were calling Lisbon number of my company while the referee was clearly stated as based in London. Waste of time and big image loss for reputable companies like Savill's who use them. Do not recommend.
