While a B.Tech mark from Germany can influence job opportunities, it's not the sole factor. Employers often consider a combination of factors, including your skills, relevant experience, communication abilities, and cultural fit. A good academic record can demonstrate a strong foundation, but practical skills, internships, and projects also play a crucial role. Networking, building a portfolio, and showcasing your knowledge are equally vital. Germany's reputation for quality education can be an advantage, but focusing on enhancing practical skills, gaining industry experience, and presenting yourself effectively will enhance your job prospects more comprehensively.
