              Sparking the Fire, Spreading the Passion

              At SupremeTech, we believe growth isn’t something that happens in isolation. True success lies in helping others rise and evolve alongside you. That's why we call it "Sparking the Fire, Spreading the Passion". When Quang Hai joined SupremeTech five years ago, he was a young professional just beginning his career. He brought with him a curious mind and an eagerness to learn, though like many new hires, he faced a steep learning curve. d. Like many beginners, he faced challenges and had a lot to learn. Luckily, he had a mentor to supported him, gave honest feedback, solved problems together, and always believed in his potential. This journey was not just about learning new skills. It was about growing, building confidence, and sharing that growth with others. We talked with Mr. Duc Tai, the mentor who supported Hai from the beginning, and with Quang Hai, who is now ready to guide the next generation. Their stories show how one person’s support can help light a spark that keeps on spreading. Sharing From the Mentor - Mr. Duc Tai What made you believe Hai had the potential to go far? Mr. Tai: Right from the start, Hai showed that he could think clearly and always tried to understand problems deeply. He didn’t just fix things on the surface. He wanted to solve the real issue so that everything could work better in the long run. He was calm, listened well, and focused on finding solutions instead of complaining. He was also very responsible. I never had to worry about the tasks I gave him. When assigning roles, do you prioritize short-term results or long-term development? Mr. Tai: I always lean toward long-term growth. If someone is in a role where they feel both challenged and supported, the results will naturally follow, and they’ll last longer. It's not just about getting things done today but building a foundation that sustains growth in the future. What do you find to be the most challenging part of being a manager? Mr. Tai: It’s finding the right place for each person. I spend a lot of time watching and thinking about how people work. When someone is in a role that suits them, they can grow at their own pace, and the entire team becomes stronger. From the Mentee Turned Mentor - Quang Hai When you first became a leader, what were you afraid of? Hai: When I was first given a leadership position, I felt nervous and unsure of myself. I wondered if I was ready and if I could earn my teammates’ trust while I still had so much to learn. Later, I realized that being a leader doesn’t mean you have to be perfect. What matters is being there for your team, being willing to listen, taking responsibility, and continuing to learn. What is the most valuable lesson you’ve learned from Mr. Tai? Hai: I learned always to be ready to take on responsibility. Mr. Tai never says no to a task, whether it comes from the company or the team. He always takes action and faces problems directly. That attitude showed me that if you want to grow, you have to step out of your comfort zone and keep moving forward. Now that you're guiding others, when do you feel you’ve truly grown? Hai: I see it in the way I listen and ask questions. I used to think a mentor had to provide all the answers. But now I know that helping someone means guiding them to find their own answers. I often ask, “What do you think?” or “What’s making this hard for you?” To me, growth isn’t about being the most knowledgeable person in the room. It’s about walking alongside others and helping them grow in their own unique way. Final thought Quang Hai’s journey is more than a story of personal development. It reflects the broader spirit at SupremeTech—a place where everyone is given the opportunity to learn, face challenges, and eventually pass on their knowledge to the next wave of talent. His transformation from mentee to mentor is living proof that when someone is nurtured with care and trust, they can grow strong enough to lift others as well. Because at SupremeTech, growth is never just about one person. And as long as we continue to support and inspire each other, the fire will never go out. >>> Read more: From Seeking The Path to Leading The Way: Phuoc’s Journey at SupremeTechAnh Duong – A Journey of Rising Above to Shine Bright
