Hadn't had great experiences with recruiters in the past, but Luke was a pleasure to deal with - friendly and personable whilst professional and honest - something I previously thought wasn't possible in a recruiter. He genuinely wants to put candidates in roles that are a suitable fit and looks to build a relationship with his clients. We've been for beers and caught up on several occasions since first working together. I'm super happy in the role Luke found me and I couldn't recommend him highly enough.
