Selection Criteria:
       
 For Computer Science, the selection is, generally based on GATE score. However, some IITs, NITs and other university colleges may conduct a written test / Interview for selection into M.Techs. In such a case, the GATE score is given 70% weightage and remaining 30% weightage is for the written test / Interview. The exact procedure will be known by referring to the information brochure issued by the colleges for admission into M.Tech. The selection criteria may vary from year to year and from college to college.

·    In IISc Bangalore, IIT Madras, Kharagpur, Roorkee, the selection is based on GATE  score.  However in other colleges apart from GATE score, a written test or interview is   being conducted  for selection into M.Tech.
  
·    If a student possess excellent rank in the GATE, then direct admission will also be given without any interview.

·    In IIIT,Hyderabad the admission is based on written test and interview.

·    For Central University, Hyderabad, selection is based on written test and interview.


NOTE: 

·    If GATE rank is within top 300, there is a chance of getting into IITs.

·    If the rank is more than 300, the students can try for those IITs where there is written test or interview for selection and also apply for NITs and other colleges depending on the merit level..


General Trend:

In open category the possibility to get the  specializations based on the  ranks, will be  generally as follows.

·   Rank Below - 200 :  Communication Systems, VLSI / Micro Electronics in IITs.

·   Rank between 200 - 300 :  Communication Systems,  VLSI / Micro Electronics  (With interview in IITs). 

·   Rank between 300 - 600 :  The remaining specializations (Refer the list given at the top of this article) in IITs and all the specializations in NIT's and Other premier Colleges like BHU, Anna University etc. (With interview and written test).

·   Rank between 600  - 1000 :  Other Universitie like Jadavpur, Pondicherry, Hyderabad, Osmania, (With written and Interview).


Stipend for M.Tech :

The stipend/Scholarship Rs.8,000/- is available for eligible candidates in the form of Teaching assistanceship or Research assistanceship etc. The teaching assistanceship may be preferred, if possible.


Non Stipend M.Tech:

Most of the IITs, NITs & other colleges have certain seats reserved in the Non-stipend category. Here, the UGC scholarship will not be given. All the expenses shall be borne by the students only. Those students who are economically sound and desperate to join IITs, can apply . Students, even with low GATE score can get good specializations.  


Special attention for SC/ST students:
 
We strongly suggest you to apply for premier institutes like IIT’s irrespective of your percentiles. Luck may favor you.


Special attention for Girls:
 
Certain universities have girls reservation, eg. Andhra Pradesh. Hence even at lower percentiles compared to boys, girls have fair chances.


Special note for Second Class students:
 
If you see the rules & regulations of various premier Institutes, 1st class in Engineering is the pre-requisite. If you apply online, your application will be rejected. Hence we suggest you to apply manually with a request letter stating your present strengths substantiating with GATE Score and your desire to do M.Tech in the respective IIT. Request them to give you a chance so that you can prove yourself. Most of the professors would like to encourage the students who are seriously interested, inspite of the above –ve point, if the GATE score is good and the student has a burning desire to join the desired specialization in the desired IIT. They may consider your application with sympathy and may give you a chance after a personnel Interview. Be bold and be positive. Definitely, you can reach your goal.


Note:
  1. Those who have got relatively low scores in the GATE, are strongly advised to apply for more number of colleges (not less than 10) so that they can get admission in atleast one college in the desired specialization.
  1. The students shall be in-touch with the daily English newspapers ( The Hindu, The Indian Express, The Times of India etc.) and Employment News for the M.Tech notifications by various colleges.
  1. All the above guidelines are only suggestive/advisory, based on the selection criteria of previous years. The candidates are requested to go through the information brochure of each college and take their own decision appropriately, depending upon their interest.

Ask yourself before going to an interview!

A big job interview is coming up and you are feeling very confident. You have anticipated the questions they might ask and have prepared some great answers. Fresh copies of your resume are sitting in your backpack. Wait a minute. Did you say backpack? Are you really going to walk into a job interview carrying a backpack? Next thing you'll say is that you're planning to wear jeans and a t-shirt. You better ask yourself these questions before you get dressed.


What should I wear?

Generally, it's a good idea to wear a suit for a job interview. Go with something simple, in a neutral tone. The more conservative your field is, the more conservative your suit should be. For example, if you're applying for a job in an investment firm, go with a navy blue or dark gray suit. 


What if my interview is for a job in a more casual setting?

It's a good idea to match your interview attire to the prospective job. If you are applying for a job working on a warehouse floor, you will look out of place wearing a formal suit. Keeping that in mind, dress a little better than you would for a day at work and make sure your clothes are neat and clean.


My interview is for a job in an accounting firm. Traditionally this field is conservative, but this particular firm may be a little more casual. How should I dress?

You can't go wrong in a suit, but if you want to give more of an impression of "fitting in" then you need to find out how people actually dress for work at that firm. One way to do this is to observe people arriving for work. Choose any day other than a Friday, which is when some companies allow more casual dress. Again, follow the rule of dressing better for the interview than you would for a typical day at the office.


Do I have to buy a new suit?

As long as your suit is in good condition and not outdated, you don't have to buy a new one. If you do decide to purchase a new suit, buy the best one you can afford and make sure you don't get anything too trendy. You want your investment to last.


What shoes should I wear?

In all instances, wear closed-toe shoes. Sandals are never appropriate for a job interview, unless you are applying for a job as a lifeguard. Black shoes match everything (yes, even your navy blue suit). Stick with a conservative style. Women should not wear very high heels.


Must I buy new shoes?

No. Shoes you've already worn are fine, unless they are in bad condition or out of style. A little shoe polish may be in order here.


What about my nails?

Your nails should be clean. A man's nails should be kept short and a woman's nails shouldn't be excessively long and should be bare or polished in a neutral color.


I love wearing jewelry. Can I wear it for the interview?

Modest jewelry is fine, but don't wear large earrings or a thick chain.


What about makeup? How much is OK?

Don't paint on the makeup. Keep it simple and use neutral colors.


What should I carry with me? a purse, a briefcase or a backpack?

By all means, leave the backpack at home. You want to look professional, not like you're taking a stroll across campus. A woman can carry a small to medium sized handbag. A man or woman can carry a briefcase if he or she wishes, or a folder or portfolio.
