PDF रिज़्यूमे डाउनलोड करें

आपके प्रोजेक्ट और कौशल GitHub से पहले ही भर दिए गए हैं। जो GitHub प्रकाशित नहीं करता - संपर्क विवरण, अनुभव और शिक्षा - वह जोड़ें और एक पेज का ATS-सुरक्षित PDF एक्सपोर्ट करें।

PDF एक्सपोर्ट एक मानक PDF फ़ॉन्ट का उपयोग करता है जिसमें देवनागरी ग्लिफ़ नहीं हैं, इसलिए उसके सेक्शन शीर्षक अंग्रेज़ी में ही रहते हैं। Word (.docx) एक्सपोर्ट पूरी तरह अनूदित है - इस भाषा में रिज़्यूमे के लिए उसका उपयोग करें।
