    Junior 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!

    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.

    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!

    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.

    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.

    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 :)

    Despite I am new member of team I can say the atmosphere here is really nice. I feel comfortable working in our office. Thanks to the training which I had I know necessary basics about IT and recruitment via LinkedIn.
