2. Admit Card: Once the application process is completed and accepted, you will receive an admit card. This card contains important information such as your registration number, exam center, and timing.
3. Entrance Exam: GATE is primarily an online computer-based test. The exam usually takes place over multiple sessions and is conducted over a span of a few days. It consists of objective-type questions that assess the candidates’ understanding of their respective undergraduate subjects.
4. Results: After the examination, the conducting authority releases the GATE results. The results are typically announced on the official website, and candidates can access their scores using their registration numbers or login credentials.
5. Interview/Selection Process: Depending on the purpose of taking the GATE exam, some institutions or organizations may require candidates to appear for an interview or selection process. This typically happens in cases where GATE scores are used for admissions to postgraduate programs or recruitment by certain companies or institutions.
6. Counseling (for admissions): If you have appeared for GATE for admission purposes, you may need to participate in a counseling process. This involves selecting your preferred institute, specialization, and sometimes attending counseling sessions for document verification and seat allotment.
It’s important to note that the specific details and procedures may vary from year to year and from one organization to another. Therefore, it is always recommended to refer to the official GATE website or the specific organization’s guidelines for the most accurate and up-to-date information regarding the interview process.
