I recently worked with Martina…
I recently worked with Martina Costantini at Storm4 for a Data Center Project Manager role. Even though I didn't end up getting the position, I wanted to share what a fantastic experience it was. Martina was incredibly professional, transparent, and communicative throughout the entire process. She provided helpful insights before my interviews and was prompt with feedback afterward. It’s rare to find a recruiter who treats candidates with such respect and care, regardless of the final outcome. I highly recommend working with them!
Isaac McGirt - Project Manager / Engineer Canidate Review
Martina Costantini has been a pleasure to work with from the very beginning of our connection on LinkedIn. She is consistently polite, professional, and highly attentive, and she has an exceptional ability to align my skills with relevant opportunities. When I share my experience, career goals, and professional needs, Martina truly listens and leads with that understanding when presenting new roles—something I greatly appreciate.
Of all the recruiters I’ve worked with, I can confidently say Martina stands out as the best. Storm4 feels like the right place to engage professionally because of Talent Acquisition Specialists like her. One of the aspects I value most is her transparency; she clearly communicates where I stand in the candidate pool and provides honest insight into my profile, ensuring I’m never left in the dark.
I’m genuinely grateful to have a recruiter I can trust, and Martina exemplifies what excellent talent acquisition should look like.

Amazing partner throughout the interview process
It was great working with Iona at Storm4 during my recent interview process. She was a wonderful partner throughout the interview and the negotiation process. Her attention to detail and clear and consistent communication helped ensure that both parties were closely in sync. Her support during the interview process was invaluable, and she provided thoughtful guidance and advocacy during negotiations as well. I felt well-prepared, well-informed, and genuinely supported from start to finish. I would highly recommend working with Iona.
Tremendous experience with Iona at Storm4
I worked with Iona at Storm4. She was looking for someone to fill a good sales role in the electrical industry. Once we connected, Iona did a tremendous job explaining the role to me and asking the right questions to make sure it was a fit for both parties. Once I was into the interview process, Iona went above and beyond with preparations and follow up for both before and after interviews. She is great at her job!
Stephanos can greatly increase your job seeking success. I am the example.
Mr. Stephanos Savva of the storm4 helped me secure a thoroughly vetted engineering position in a green tech battery business.
He assisted me in the every step of the interview process with strong passion for my success, with strong analytical skills for instantaneous feedback of my performance, with correct requirements or expectations set for my next interview stage.
He effectively communicated with the hiring team to smooth out any potential delay or misunderstanding as well as professionally covered my entire interviewing process with appropriate mount of guidance from initial phone screen, technical evaluation, references vetting till my final acceptance of the offer letter.
I strongly recommend Mr. Stephanos Savva and his firm, Storm4, 's recruiting services to any job seekers with my 100% satisfactory.

Iona with Storm4
Iona made the experience of exploring, and ultimately taking, a new opportunity so easy. I was set in the job I had but when she reached out and explained the role she was helping to fill, I was immediately put at ease and trusted her opinion. Along the way she constantly checked in to see how I was feeling about it - not purely in a work pov, but more at a personal level. I always felt like she truly cared about what was best for me.
