Gisu is a truly unique career consultant who combines deep professional expertise with an infectious passion for growth. He has an exceptional ability to read shifting market trends and translate them into practical, actionable advice for juniors and students entering the workforce. What sets him apart is his proactive approach to the 'AI Native' era; he never shies away from learning new technologies and remains dedicated to continuous research. As both a colleague and a mentor, he constantly inspires those around him to strive for excellence. I have no doubt he will continue to be an invaluable asset to any professional community.

I had a very insightful conversation with Gisu through the start-aws Korean tech community, where he shared perspectives that genuinely changed how I understand professional networking in the Korean tech ecosystem. As a recruitment agent, Gisu explained how tech events, sponsors, judges, and experienced professionals are often connected in ways that are not immediately visible from the outside. His explanation of how relationships, community presence, and participation shape professional opportunities gave me a completely new way of seeing how the Korean tech community functions behind the scenes. What stood out to me was his ability to clearly describe the structure of networking in Korea and the mindset of hiring managers, especially within the tech field. I really appreciated the time he took to share these practical insights from his experience. I would recommend Gisu to anyone who wants to better understand how the Korean tech ecosystem and professional communities actually work in practice.

Recently, I urgently needed to recruit new researchers. However, it was a particularly challenging time, as I was dealing with overlapping responsibilities such as project management and research funding applications. During this period, Mr. Gisu Jung provided exceptional support and guidance. First, he took the time to thoroughly understand my situation and offered thoughtful advice on the type of talent that would best meet my needs. In addition, Mr. Jung documented key considerations for the overall hiring process—explaining how companies typically run efficient recruitment procedures and what smaller research labs like ours should keep in mind when hiring new staff. He also helped us establish clear and practical criteria for both the CV screening and interview stages, carefully tailoring them to align with our specific goals and circumstances. Thanks to his guidance, I was able to identify suitable candidates with far greater confidence. While all of his advice was extremely valuable, I found his suggestions on interview questions particularly insightful. He not only selected appropriate questions for each candidate but also explained the purpose behind each one and what kind of information it could reveal. I believe that anyone seeking career advice or guidance in recruiting talent would greatly benefit from Mr. Jung's expertise. His insights are valuable not only for job seekers but also for those responsible for hiring.

I had the opportunity to collaborate with Consultant Gisu Jung while preparing an interview workshop for IT job seekers. Gisu is a consultant committed to helping candidates, demonstrating clear responsibility and ownership in planning meetings. His communication is precise and clear. While his written communication can be lengthy, it shows how much thought and time he puts into his work. In the workshop, he delivered the key message that "Interviews are conversations", helping students understand why they feel anxious and how to approach interviews confidently. His skills were especially evident during mock interviews—he showed students how to grasp the core mechanisms of interviews regardless of industry or role. Although he specializes in applications, I can confidently recommend him for interview coaching as well. Working with Gisu was a valuable learning experience for me as well.

Gisu delivered an insightful personal branding session at the Students@AI Seoul Hackathon, engaging both Korean and international university students. He clearly pinpointed key elements of branding and eagerly shared his expertise with young adults preparing to enter the job market. Gisu was proactive throughout the process—offering thoughtful suggestions and thoroughly preparing for the session. It was a pleasure working with him!

I am writing this recommendation to express my deepest gratitude and sincere admiration for the incredible mentorship Gisu provided during my job seeking period in South Korea. His unwavering dedication to excellence, coupled with his expertise in resume editing and his ability to inspire and empower those around him, played a significant role in having my application accepted in three big Korean companies.

Before working with Gisu for the first time, there were many doubts. I was that desperate, and I contacted him thinking of 'grabbing straws' in Korean. I didn't expect his help to make a massive difference to me, but it made a significant change enough to destroy that expectation. I do not doubt that the results that will be available in the future will be more significant and more spectacular than the results obtained after his consultation. Thank him for his help. And good luck to those of you who will receive his help in the future.

I highly recommend Gisu Jung to who needs any professional advice related to career. I have been living in New York for 15 years and came to Korea for my career change. While I was struggling with new career culture, I got connected with Gisu Jung. From the beginning, rather than other consultants which just start with explanation of what kind of service they will provide, he first tried to understand my background and experience. With my first explanation, he understood exactly where I was having a hard time and which guidance is needed. While having the consulting service, he tried his best not only with career advisement but also to explain what I need to be aware of. I was amazed that he was actually studying himself to gain the info for me. After the service was done, he was willing to be in touch to help any further issue even after my satisfaction was maximized. Please do not hesitate to connect with Gisu Jung since he will build your trust first and you will be surprised with his attitude & service.

I have been a client of Gisu, Jung for some years. I have always been satisfied with his service of resume consulting for me. He speaks frankly and truly, more than any other resume consultant. I was frequently surprised when I acknowledged he described my resume exactly and properly and reasonably—more than myself. So I have got many good results, thanks to his earnest and unbelievable resume consulting service. I like him very much, as a friend and a business partner.

When I was preparing for my first job in my life, I learned how to write a resume properly and got many pieces of advice related to interview preparation through him. In that way, I was successfully accepted into many companies by his endeavor. When I got consulted with him, I could catch what I am missing and the information I needed. Even recently, I am getting a lot of help when I prepare to seek new job opportunities. He gives me accurate and fast feedback against my personal tough points than other advisors like recruitment consultants. With current situation analysis through a cool brain, he always gives good advice for your great result. For those who aim to improve their career, he will take care of every process from resume to interviews until you succeed.

At the time I requested Gisu for a service, I was completely lost in my career path. But soon as he heard my situation, he caught what my concern was and guided things I needed to do very clearly. Gisu has magnificent insight and is deeply empathetic, which gives me motivation to take action. Mostly I talked about my career, but more than that his feedback about me as myself helped a lot. It is good to have someone around tell me what kind of personality I have. His way of conversation is sometimes comforting, and allows rational choices to be made in difficult situations. I am fully satisfied with his service and strongly recommend Gisu for anyone who wants to go further in their career.

I had worked with Gisu at Mensch consulting from 2017 to 2019. Based on what I had seen for the past 2 years, I think he always tries to set up an efficient plan lined to achieve his personal and business goals, and he is excellent in communicating with the candidates and clients. Furthermore, he is highly interested in self-development as a headhunter as well as a human-being. After work I had seen him study further about communication skill and the job market. All in all, it was fun working with him and I learned a lot from him.

Gisu and I initially connected over LinkedIn when I needed additional information on the recruiting market of Seoul. He was informative, open, and thorough in our correspondence and played an integral part of helping me build out a network here while giving me a lay of the land. Beyond that, he is a diligent worker and someone that I consider a business colleague as well as a friend. He is a go-getter and will be a fantastic resource for anyone trying to find a job or develop their business skills.

My company wanted someone with rich experience in overseas business, so I visited a headhunting company to get some help. Gisu Jung was the head hunter in charge of my company, and recommended many applicants suitable for us. Although I worked with him for about 3 months, he showed a full of passion in his work. He always tried to find right applicants as soon as possible, so that my company did not have to wait. Above all, he welcomed any feedback about the applicants, and based on feedback, he introduced better applicants all the time. Finally, we found a good employee he introduced, and he is in charge of very important work now. Based on my observation of his ability and attitude, I strongly recommend Gisu Jung.

From the past experience I had with Gisu, I was pleasantly surprised by the way he put his efforts on his clients. He was one of the most self-motivated and detail-oriented people I met. Gisu was always trying to bring out the best outcome when dealing with my job conditions before my requests. As I worked with him finding my job position, I could feel his passion and energy toward his work. Even after I got a job, Gisu didn't forget what he had been through with his clients and always gave me a regular call to check my working conditions. I would like to express my strong recommendation for Gisu.

He suggested me a QA manager position in Renfro Corporation Korea branch, and I finally got an offer to join. He had outstanding communication skill—not just speaking well, he was good at data analysis and showed proper expectations based on the data he had for me related to company information. He knew which important data matters to me, like work-life balance or actual work environment, and clearly answered or at least tried hard to find answers to my main questions. Emotionally and technically, I think he was a good headhunter for me.
