About the Founder Hello, I’m Mr. Shi, founder of csoahelp.com. I’ve specialized in North American tech interview coaching for over five years, helping countless clients achieve their dream offers from top-tier companies.
At this stage, I’ve removed my personal background details because our brand speaks for itself. We’ve coached graduates from CMU, Stanford, and top Chinese universities (Tsinghua, Peking, etc.), and even interviewed teachers with elite backgrounds — most didn’t meet our standards.
Our instructors spend 4+ hours daily on student support, increasing to 7+ hours during peak season. We emphasize real skill over pedigree — and it shows in our near-100% satisfaction rate and strong reputation across platforms. Give us a chance — and we’ll change your career destiny.
