#वैकल्पिक_विषय_का_महत्त्व 

👉यह कहना पूर्णत: सही नहीं है कि सामान्य अध्ययन 1000 अंकों का है और वैकल्पिक विषय सिर्फ 500 अंकों का, इसलिये अभ्यर्थियों को सामान्य अध्ययन पर ज़्यादा बल देना चाहिये। 

👉ऐसा कहने वाले  शायद वैकल्पिक विषय के रणनीतिक महत्त्व को नहीं समझते। इस परीक्षा में यह बात बिल्कुल मायने नहीं रखती कि किसी अभ्यर्थी को कितने अंक हासिल हुए हैं। महत्त्व सिर्फ इस बात का है कि किसी उम्मीदवार को अन्य प्रतिस्पर्द्धियों की तुलना में कितने कम या अधिक अंक प्राप्त हुए हैं। 

👉विगत कुछ वर्षों के परीक्षा परिणामों पर नज़र डालें तो आप पाएंगे कि हिंदी माध्यम के लगभग सभी गंभीर अभ्यर्थियों को सामान्य अध्ययन में 325-350 अंक प्राप्त हुए (2014 की सिविल सेवा परिक्षा में निशांत जैन ने एक अपवाद के रूप में 378 अंक प्राप्त किये थे)। इसके विपरीत, अंग्रेज़ी माध्यम के गंभीर अभ्यर्थियों को इसमें औसत रूप से 20-30 अंक अधिक हासिल हुए, जबकि वैकल्पिक विषय में लगभग सभी गंभीर अभ्यर्थियों को 270-325 अंक हासिल हुए। इस औसत से वैकल्पिक विषय का महत्त्व अपने आप स्पष्ट हो जाता है। ध्यान रहे कि ये लाभ आपको तभी मिल सकता है जब आपने वैकल्पिक विषय का चयन बहुत सोच-समझकर  किया हो। 

उम्मीदवारों को वैकल्पिक विषय वही चुनना चाहिए जो उनके ग्रेजुएशन में सब्जेक्ट हो.! #जिस_विषय_में_उनकी_रुचि_है_वही_वैकल्पिक_सब्जेक्ट_को_चुनना_चाहिए! 

       सिविल सेवा मुख्य परीक्षा में चयनित अभ्यर्थियों की संख्या विज्ञापित सीटों की संख्या से 2.5 गुना होती है! यानी लगभग 15000 में से 2500  ही इंटरव्यू के लिए चयनित होते हैं. ये सिविल सेवा का कठिनतम चरण होता है और यदि यहाँ सिलेक्शन हो गया तो फाइनल सिलेक्शन के चांसेस बहुत बढ़ जाते हैं!

#Personality_टेस्ट_या_IAS_इंटरव्यू

 इंटरव्यू, सिविल सेवा मुख्य परीक्षा का दूसरा भाग होता है! इसे पर्सनालिटी टेस्ट कहते है!यह इंटरव्यू कुल 275 मार्क्स का होता है. इसे सामान्य भाषा में IAS इंटरव्यू भी कहते हैं. इसका सिलेबस निर्धारित नहीं है तथा आपके Detail Application Form (DAF) से अधिकांश प्रश्न पूछे जाते हैं! इसलिए DAF को पूरी सावधानी और पूरी सच्चाई के साथ भरनी चाहिए.!

  IAS इंटरव्यू के लिए अभ्यर्थी को UPSC की Delhi स्थित धोलपुर हाउस बिल्डिंग में आना  होता है. यहाँ अभ्यर्थियों के सभी ओरिजिनल डाक्यूमेंट्स का वेरिफिकेशन किया जाता है तथा एक कॉमन हाल में बैठा दिया जाता है. UPSC के मेम्बेर्स की अध्यक्षता में एक इंटरव्यू पैनल बनाये जाते हैं जो की अभ्यर्थियोंअ का इंटरव्यू लेते हैं. इंटरव्यू पैनल में देश की विभिन्न क्षेत्रों  से जुड़े दिग्गजों को आमंत्रित किया जाता है. IAS Interview में अभ्यर्थी का confidence, attitude तथा प्रॉब्लम सोल्विंग स्किल्स चेक की जाती हैं. यहाँ अभ्यर्थी की personality का सब्जेक्टिव असेसमेंट किया जाता है तथा अधिकतम 275 मार्क्स में से मार्क्स दिए जाते हैं!

#IAS_Toppers_के_Interview_अनुभवों_को_जानें

सिविल सेवा के इंटरव्यू लगभग 20 दिन तक चलते हैं तथा इंटरव्यू ख़त्म होने के 10 दिन के बाद ही फाइनल रिजल्ट आ जाता है. फाइनल मेरिट लिस्ट इंटरव्यू तथा  सिविल सेवा मुख्य परीक्षा लिखित के मार्क्स मिलकर बनती है. इसका अर्थ यह है की अधिकतम 2025 मार्क्स में से फाइनल मेरिट लिस्ट बनती है जिसके आधार पे सर्विसेज प्रदान की जाती है. लगभग 100 रैंक तक के अभ्यर्थियों को IAS सेवा मिल जाती है!

रिजल्ट के कुछ दिन बाद UPSC अपनी रिकमेन्डेशनस को Ministry of Personnel को भेजता है जिसके बाद ही सबको appointment letter जारी किये जाते है. जो अभ्यर्थी फाइनल रिजल्ट में जगह नहीं बना पाते हैं उन्हें पूरी प्रक्रिया से फिर से गुजरना होता है!

तो यह था सिविल सेवा के फॉर्म भरने से लेकर सिलेक्शन तक का सफ़र आशा है आपको यह लेख पसंद आया होगा !
