    ex IT Recruiter

    Marcin has demonstrated a high level of professionalism during the recruitment process. His approach was personalized, thanks to which I felt well-informed and taken care of during the whole process. He's organized multiple check points to make sure everything was going smooth. Marcin has been extremely helpful and he's definitely a great person to work with!

    I highly recommend Magda Brdeja as a recruiter! She's fantastic at communicating and keeping everyone informed throughout the process. Magda is incredibly organized and ensures that everything runs smoothly and efficiently. Most importantly, Magda is fully committed to finding the best candidates for the job. If you're looking for a recruiter who's dedicated and great to work with, Magda is the one!

    Carmen is a professional, and at the same time, very empathetic and helpful. Constant contact and support at every stage of recruitment is what you can expect when working with Carmen. I highly recommend!

    Working with Marcin has been a refreshing pleasure. Through my whole recruitment journey he has been very proactive not only in terms of finalizing the deal but also the aftermath and how things are after some time has passed. He is always responsive, very communicative and friendly. I must say it has been so far the best recruitment experience i have had to this day and i wish all my previous ones had been like this.

    One of the nicest and coolest recruiters I've had a chance to cooperate with. The recruitment process was clear and smooth. Kamila is also very communicative and supportive. Awesome job!

    Ms. Ewelina conducted the recruitment in a very professional manner. From the first minutes of the conversation I had an opinion of Ms. Ewelina as a person who is accurate, reliable, very punctual and delivers projects to the end.

    Marcin Zająkała is a great person. The best recruteir I've ever known. He presented me an offer that was very good for me and (I supose, also good) for the company where I work thanks to him. He was in the right place at the right time. Brilliant intuition. Thank you!

    Weronika help me a lot when I was searching for a new company to work. She found me, had a talk and help me to connect with current employers. She were werty helpful trough the whole process of recruiting. It was great to have her coordinating me.

    Wonderful competent person very opened to people. He supports candidate at the entire recruitment process by offering his help at every stage and provides truthfully (and very useful) feedback. It was pleasure to meet and work with him.

    Weronika took care of my recent recruitment. With a professional, substantive, and interesting offer, Weronika got me to move on to a new job. After three months, I was already on board. A nice touch was the onboarding aftercare. Weronika called and asked if I was satisfied with the cooperation. I recommend cooperation with Weronika!

    I had a pleasure to go through recruitment process with Marcin. He was very professional from initial call to signing the contract. I had his full support and always was and kept up-to-date with application status. I can honestly recommend him as one of best recruitment experiences I had in my career. Hope we can work again in the future.

    Transparent and to-the-point communication, quick actions and no-bullshit approach. Thats what makes Marcin stand out from other headhunters. Highly recommended recruiter.

    Very creative and flexible attitude. Marcin is fast-thinking, full of passion and always direct to discussed goals. Always keep in touch by phone to provide better options for future development. I will recommend Marcin. Best regards

    One of the kindest and most proactive recruiters I've had the pleasure to work with. Thanks to a professional approach, the entire recruitment process went without any problems. I have the impression that Kamila is the only recruiter who actually reads the candidate's profile and matches offers in the right way. Thank you for the great collaboration and I recommend her to anyone looking for their new professional position!

    Working with Milena during my recruiting process was the best experience with a recruiter I ever had in my career. Always making sure meetings, calls and communication in general was fast and effective. She kept me updated and moved on with the process allowing me to still focus on my NOW old job. In terms of professionalism, ethics and involvement she was the #1 by far. Would highly recommend for any software developer that is looking to boost their career. Thank you Milena for all your help!

    I would describe the recruitment process conducted by Ms. Ewelina as a sheer pleasure. The efficient organization of meetings, exchange, and conveying of information was a daily routine. You never had to wait long for a response from Ms. Ewelina. As a person who was recently under her recruitment care, I am definitely satisfied.

    Magda is a great recruiter. She is very friendly, very communicative and extremely helpful. She was giving me feedback through the every stage of recruitment process. From my perspective it was the best recruitment of all recruitments I had. And not only because of the fact I found the job, but also of the fact that Magda kept everything professional and she always kept the word she said and always gave me feedback when she said she would. I sincerely recommend her with my whole hearth and wish her everything good in her career.

    It’s rare that one comes across a standout such as Marcin. Since I was his customer I'm entitled to speak up how flawlessly and classy the whole recruitment proceeded. That skillset often takes years to develop among customer service professionals, in this case however it seemed very natural. Everybody wants to hire someone who not only gets the job done, but also is great to work with. One more thing I don't like wasting my time - for instance to recommend people who don't deserve it :)

    At, I worked for almost 2.5 years, and I can recommend this place to anyone considering joining the team. While I was working here, I greatly appreciated the flexibility. Every day, I could start within comfortable time frames. If I needed a longer break during the day, it was never a problem to make up the hours later. I received my salary on time. The atmosphere was informal, and I have very fond memories of company events. I recommend working with Marcin.
