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.

VP, Finance & Admin

We’ve partnered with Steph and Storm4 on several searches, and Steph has been excellent every time. He took the time to understand our hiring needs and the nuances of each role. Even when the search was challenging, he worked diligently to find strong, relevant candidates. His communication was always quick and clear. We’ve had a great experience working with him and Storm4 and would happily do so again.

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.

Great Experience with Storm4

It was a pleasure to work with George White. He was always transparent with every step in the interview processes and a great coach. Everyone I spoke with at Storm4 was friendly and professional. I couldn't recommend them more!

Great experience with Alex and Oscar

Great experience with Alex and Oscar. They presented the job opportunity, and it was exactly the job I wanted. Alex gave me good info prior to the interviews and excellent feedback after the interviews. They gave me good advice on the compensation plan. I appreciate everything they did, this job is life changing!

Great team to work with

Natalia, Joe and Steph make a great team. Their coordination with others and within their group are excellent. They keep you posted with events in real time and present clear picture between the employer and the candidates.

Amazing experience! Super helpful!

Having Natalia Filipek as my recruiter for my most recent job was amazing. She helped to push my resume through to the hiring team and super helpful along the way by giving me insights and scheduling the meetings. Worked super hard and always reached out to let me know how everything was going and what the job was looking for so that I had a better understanding what I needed to focus on during the interview. If I had any questions she was just a phone call/text away. Made the whole process super easy and straightforward. She’s the best! Couldn’t have gotten the job without her! I highly recommend Storm4 and Natalia Filipek if you ever need a job!

Great Care

The Storm4 team was incredibly responsive and professional - with me every step of the way throughout the interview process to not only continuously gauge my level of comfort with the prospective employer, but also to occasionally advocate on my behalf when needed. They took great care to ensure a proper fit.

Storm4 and Anthony at Storm4 was great to work with. They are organized and provide great candidates. When they make mistakes in what they provide, they take feedback very well and the new results show it. They are remote out of country, but you wouldn't know it from the hours they work and the quality of candidates

Great experience

It was a fast process, most recruiters have an initial screening and then fall off the face of the earth. This wasn’t the case here, had a screening then started the interview process and landed the job within 3 weeks. Awesome experience

Exceeded My Expectations

I couldn’t be more pleased with my recent hiring experience. I had the good fortune of working with Natalia who made me feel comfortable from the first phone call. Communication is so critically important and Natalia went out of her way to make sure the process moved along efficiently and that I always knew what to expect. Her ability to provide clarity around the process and her responsiveness to questions/concerns was reassuring. Natalia also demonstrated a willingness to advocate for my best interests.

I don’t think my experience could have been any better.
