GATE Score-All colleges prefer applicants with a GATE score. Colleges apart from the IITs, NITs, etc. at times conduct their own admission test, but it is highly recommended to appear for the GATE exams preference is always given to the GATE applicant.
Written Test- This test is conducted for students who do not appear for the GATE exam and are yet eligible to apply for M.Tech courses (basically admission to M.Tech without taking the GATE). Most colleges do not have a written test as a part of their admission process.
Interview Round- This round tests your technical skills, basics and concepts about the desired M.Tech course and a couple of HR/personal questions. If you have not managed to score in the GATE exam, this is a bonus round. It varies from college to college, but most colleges have started conducting an interview session.
Engineering Academics- Even though GATE exam is based on the entire syllabus of engineering, few colleges prefer to go through the undergrad academic record of the candidate. So, if you've preformed excellently, the balance tilts in your favor.
General Flow of M.Tech Admission Process:
Appear for GATE. Keep track of notifications announced by various colleges offering M.Tech program. This might be the most gruesome part, as there is no Centralized Admission Process. Fill up the application form (mostly online) along with the prescribed application fee before the deadlines. Once the results are declared and your name appears in the final list, confirm your admission by paying up the tuition fee.(If there is an interview round)Once the shortlisting of applications are done, selected candidates will be called for an interview round after which then the final list of selected candidates for M.Tech program will be declared.
