There is no shortage of fantastic recruiters to choose from. There are those that specialize by sector or by function, there are large multi-site high street agencies, global players, and single-site niche businesses. So how do you determine which one will be best to support your business?​We believe the most important element is to choose a partner you trust. If you don't immediately feel they understand your unique situation and they don't go out of their way to really understand your purpose, speak to another. Your reasons for choosing may sometimes be difficult to articulate, however, after speaking you will quickly know which company is best to represent your brand.​And finally, whilst price is an important element in choosing a supplier, make sure you're calculating all the costs - not just the fee %. The company that delivers you a great shortlist the first time round, who organizes your stakeholders and minimizes wasted time will save you thousands over the course of the project.Ultimately, the best way to measure us is to speak to us. However, in the meantime here are a number of frequently asked questions that may just help you decide to include us on your shortlist!
