## CWC 2026 written examination — official post code 05: Assistant Manager (Engineering) — Electrical The CWC 17 October 2026 advertisement specifies an online examination of 200 objective questions (200 marks) plus two English descriptive questions (30 marks). Total: 202 questions, 230 marks, 180 minutes. The examination date is yet to be notified. ### Section-wise test blueprint (separately timed) | Section | Questions | Marks | Medium | Time | |---|---:|---:|---|---:| | Professional / Subject Knowledge | 60 | 60 | Hindi and English | 55 min | | General Awareness | 40 | 40 | Hindi and English | 20 min | | English Language | 40 | 40 | English | 25 min | | Reasoning & Computer Aptitude | 30 | 30 | Hindi and English | 25 min | | Data Analysis, Interpretation & Quantitative Aptitude | 30 | 30 | Hindi and English | 25 min | | Language & Comprehension Abilities — Descriptive | 2 | 30 | English | 30 min | | **Total** | **202** | **230** | | **180 min** | ### Scoring, qualifying rules and next stage The Professional/Subject Knowledge section (where applicable) and the descriptive English paper have minimum qualifying thresholds: UR 40% and OBC/EWS/SC/ST/PwBD/Ex-Servicemen 35%. These are qualifying thresholds, not final selection cutoffs. Separate sectional and aggregate cutoff scores may be applied by CWC. Only objective-test answers attract a penalty of one-quarter of the question marks for an incorrect response; blank responses attract no penalty. For codes 01–06, shortlisted candidates undergo document verification and interview (maximum shortlist ratio 1:5); interview has 30 marks and the final online-test/interview weighting is 85:15. Interview minimums: UR/EWS 50%, OBC 45%, SC/ST/PwBD/Ex-Servicemen 40%. All section times are separate; the total paper lasts 180 minutes. Official examination date has not been announced. ### Official subject syllabus (indicative, as published by CWC) **A.
