They were always helpful and easy to deal with, and helped me land a new role. ### Google review - Source: Google - Rating: 5.0/5 - Date: 2026-09-07 > User-generated opinion > George is outstanding and very professional, he takes a very human approach to recruiting. ### Google review - Source: Google - Rating: 5.0/5 - Date: 2026-09-05 > User-generated opinion > Working with Harry and OpenSource was a great experience from beginning to end - they perfectly matched me with my new job, helped fight to get me the compensation for it that I deserve, and we had fun doing it\! > > I met Harry in early 2025 \(just on the cusp of AI sloppifying the labor/recruitment market\), I was already employed as a devops engineer elsewhere, but I was looking for something new via both recruiters and the jobs boards. Harry connected with me on LinkedIn with an engineering job \(senior oncall engineer, devops/SRE at a fintech firm\) that was incredibly well suited for me on all fronts: skills match, industry match, leveling/compensation match, and geographic match \(at the time I was living and working in the US, and Harry presented me with an opportunity that was flexible and workable from both the US and the UK\) > > We met for a quick intro over Zoom, Harry was super nice, accommodating, friendly and cool, and he knew what he was talking about - a true professional\! We discussed the job, my fit, my interest, my comp expectations, and Harry communicated all this back to the employer - and clearly quite well\!\! > > Something I really appreciate about Harry and everyone at OpenSource Recruitment: since our initial meeting, several months went by with no word from the employer. A lesser recruitment firm probably would have dropped the ball, forgotten about me, or moved on, but Harry & co stayed on the case with me, communicated proactively, and got me into interviews a few months later as soon as the employer was ready to engage. > > After passing all my interviews and entering into the compensation negotiations phase, Harry and OpenSource absolutely came in clutch. Harry helped me negotiate a significantly higher salary than was originally discussed, putting me at the top of the comp band for the position; Harry and OpenSource advocated for me and worked as my liaisons to the employer - having them there to back me up was essential, and I don't think I could have pulled it off without them\! > > Harry and OpenSource are the recruitment GOATs, and whenever I'm looking for new work I will be hitting them up again - highly recommend\!\! ### Google review - Source: Google - Rating: 5.0/5 - Date: 2026-09-04 > User-generated opinion > I had a great experience working with Harry. He always supportive and easy to talk to. What really stood out was that he continued to check in even after I started my new role. I’m really grateful for all his help and would highly recommend him to anyone looking for their next opportunity. ### Google review - Source: Google - Rating: 5.0/5 - Date: 2026-09-04 > User-generated opinion > Working with OpenSource recruiting team especially Harry was a great experience - they were responsive, understood exactly what I was looking for, and made the whole process smooth and professional.
