Selection Process of Assistant Foreman

I. Eligible candidates meeting the minimum eligibility criteria as on the Crucial Date, as specified under this Notification, will be required to appear for a Computer Based Test. The selection will be based on a candidate’s relative score in the Computer Based Test.

II. Candidates will be allowed to appear in the Computer Based Test merely on the basis of their declaration regarding their eligibility as mentioned in the online application form. Scrutiny/ Verification of the claims of the candidate(s) of their eligibility for a post applied will be done post declaration of results of the Computer Based Test. Such scrutiny/ verification will be done only for those candidates who shall pass the Computer Based Test as per the laid down cut-off marks (Minimum Qualifying Marks).

III. Computer Based Test will be conducted separately for each post. The Computer Based Test will be of 100 Marks for 90 minutes duration (in one sitting), comprising two sections (Section-A & Section-B); Section ‘A’ will consist of technical knowledge (discipline related) with 70 multiple choice questions (MCQs) and Section ‘B’ will consist of General Knowledge, General Awareness, Reasoning, Verbal & Mental Ability and Quantitative Aptitude with 30 marks multiple choice questions (MCQs). Each question will carry 01 mark and there is no penalty for wrong answer. No marks will be awarded for un-attempted questions. The question paper shall be bilingual i.e. in English and Hindi only. However, in case of any error/ambiguity in Hindi version, the English version of the question shall be valid and final.

TEST CITIES:
The Computer Based Test will be held at Test Cities as mentioned in the online application form. Candidates may opt for the Test Cities from the list as per their preference and the same cannot be changed after the online application form is submitted. NCL reserves the right to allocate any Test City or change the Test City opted by the candidate. NCL reserves the right to add or delete any Cities(s) from the list based on the number of applicants.
