Callum was incredibly helpful, supportive, communicative and overall a wonderful person to work with. Could not ask for more!!!!!!
I had an outstanding experience working with Callum as my recruiter. From start to finish, he was professional, responsive, and genuinely invested in helping me find the right opportunity—not just any job.
Callum took the time to understand my goals, kept me informed throughout the entire process, and provided helpful guidance every step of the way. What really stood out was how approachable and supportive he was—he made what can be a stressful process feel smooth and manageable.
Thanks to his effort and dedication, I landed a role that I’m truly excited about. I can’t recommend Callum highly enough to anyone looking for a recruiter who actually cares and delivers results.
Working with Callum was one of the most positive recruitment experiences I’ve had. He really listened to what I was looking for and guided me through the entire interview process step-by-step. Even after receiving an offer and starting the new position he continued to check in with me periodically to see how things were going. Highly recommend Iceberg and Callum in particular.

I talked with one of HR her name is remya. For helping me to
Get a job in Canadian market.
However instead of giving the reply and the clarity regarding she or the agency is ready to help or not . She just ignored.
Taking all the information and then not responding back was just irresponsible behaviour.
Never ever recommend iceberg to anyone.

I worked with Archie when he recruited me for a role at a start-up. Archie was a great recruiter, always available to answer questions and I felt that he really went into the negotiations with my best interests front and center. Although I didn't end up taking the role, I would happily work with Archie again!

Tom Chapman reached out to me and accompanied me throughout the extensive hiring process journey. He helped me understand the company and provided assurance and tips for the interviews. I joined the hiring company and confirm that it is indeed a good fit both ways. I would highly recommend working with Iceberg.

very easy to manage payments and get all the information I needed even if they had to repeat. I am bilingual so we communicate in both languages if we didn't understand. Made sure everything was cleared with management too. overall was very happy talking to Yuri today. on a plus side he even help me out to write his name by saying like the astronaut. such a great way for me to write it!

Iceberg was a great company to work with !
the staff was highly attentive and professional which led to a very smooth and consistent hiring process. I have no notes and nothing but gratitude for the team in this process.

I've worked with Tom Chapman for several years, and his professionalism is second to none. He's proactive, friendly, and truly exceptional at what he does.
Tom helped me secure an excellent role, working diligently with both me and the employer to remove roadblocks and ensure clear communication throughout the process. His ability to translate technical requirements into business value and vice versa is rare among recruiters and made a significant difference in reaching the right outcome.
Tom is one of the most understanding and capable recruiters I've encountered. I highly recommend him to anyone looking for a recruiter who genuinely partners with you rather than just filling positions.

Archie is an amazing recruiter. It was a 2+ month long process but he made sure to keep me in the loop & get everything moving forward. I am 3 months into my job at Tower and I am incredibly grateful. Thank you all!

My experience working with Callum was amazing. He worked with me and answered all my questions with an awesome energy and professionalism throughout every step of the process. Wonderful experience all around. Highly recommend.

I had a great experience with Callum from Iceberg. He contacted me with serious opportunity (in contrast to other recruiters who have reached out with something that would be a step down from my current role) and explained why he thought it would be a good fit. He was informative, responsive, and involved throughout the interview process. When I ultimately turned down the offer, Callum was understanding and we ended things on a good note. I would definitely work with Iceberg again in the future.

Callum was super professional and gave great advice from the beginning. He was honest and only put me forward for those we agreed and truly matched my requirements. He managed the process really well and helped when I had multiple offers to manage. Couldn’t recommend enough.

I worked with Callum Nevill @ Iceberg on all aspects of a new strategic sales leader role in the US with company which is a top tier technology leader. His professionalism and follow up and his end client relationship was second to none. His personal nature and 24-7 “get it done right attitude” and his client partnership was second to none.
His personal and technical nature and “attitude of building and leaving no stones unturned” , raises the level of all aspects of the recruitment engagement. I so very highly recommend Callum and the Iceberg teammates!! Thank you Callum!! jim s

I had an outstanding experience working with Callum Nevill. His deep market knowledge and clear understanding of employer needs made the entire process seamless and strategic. He offered insightful guidance at every stage, coaching me through each step with honesty, patience, and practical advice which genuinely elevated my candidacy.
Although I ultimately didn’t get the role (it wasn’t the right fit for either party), Callum’s professionalism never wavered. He was transparent, supportive, and truly committed to ensuring the match made sense on both sides.
What stood out most was his accessibility. He was always available to answer questions, provide updates, and talk through decisions. It never felt transactional; he was genuinely invested in my success, not just filling a position.
Even without an offer, I walked away feeling confident, informed, and valued. I highly recommend Callum to anyone seeking a knowledgeable, thoughtful, and genuinely professional recruiting partner.

Great experience with Iceberg while interview for a new role (got the role). Tom Chapman was very helpful through the process and made sure I was prepared for every interview along the way. Very professional and supportive.
