    What is Electronics and Communication and its Scope?

    GATE Electronics and Communication Discipline develops passive electrical components. Under this discipline, there are various subfields including signal processing, telecommunications engineering, electromagnetics, control engineering, computer engineering, and VLSI design engineering, and instrumentation engineering.

    Scope after GATE 2023 EC Paper

    The number of students answering GATE in Electronics and Communication Engineering (EC) is growing rapidly every year. This is because the Master's courses now require a GATE score and all of the PSUs also employ through GATE. 

    Some students are interested in pursuing M.Tech from IITs / NITs in various streams such as Communication Systems, Analog Circuits, Electromagnets, Digital Circuits, Networks, and Control Systems; while others try to get a job at PSUs such as IOCL, HPCL, RITES, EIL, NHAI, and DMRC, to name a few. Thus, the significance of the GATE EC exam and the different opportunities through GATE are important to understand.

    1. Job opportunities in top PSUs

    • Nearly 100 PSUs working in the country such as IOCL, ONGC, HPCL, NHAI, DMRC, BHEL, SAIL, NTPC, consider the GATE score as an important criterion for electronics and communication engineer recruitment. 
    • A career at a good PSU means you will keep in touch with recent advances in engineering and work on exciting country development projects, along with having benefits of the security provided by government jobs. Check PSU Recruitment through GATE

    2. Study M.Tech after GATE 2023

    • One of the most common ways to proceed is to apply for M.Tech at the IITs, IISc, and NITs after the GATE test has been cleared. This can be an important step for students who have dreamt of studying at top institutes like IITs and NITs in the country. 
    • During the two years of your Master's program, you will also be eligible for the MHRD stipend, provided you have a strong GATE score. 
    • Also, if you apply to other state, regional or private colleges that do not have GATE scores as their primary selection criteria, having a good GATE score would still give you an advantage over the other candidates. 
    • Upon completing M.Tech, you can apply to private jobs with good packages in the electronics and communication domain.  Check GATE 2023 COAP Counselling

    Ans. Many GATE toppers leave PSU and join NITIE, instead of IITs because it offers better placements. Usually, students with good scores join  ONGC, NTPC, BHEL, IOCL, and others. Despite the good salary, PSU jobs can get monotonous after a few years. So, the top rankers start looking for better career options. If they wish to do an MBA, they need to prepare for CAT. Some do prepare for CAT, but many join NITIE as it is an easier option. NITIE takes admission through GATE and the GATE score is valid for 3 years. So, they can easily get admission based on their GATE score.  Also, the institute has a great placement record. During the NITIE Mumbai placement in 2022, the average CTC offered was INR 25.41 LPA. The video below will convince you further to join NITIE Mumbai Overall, its the excellent opportunities offered by NITIE that makes mant GATE toppers leave PSU and join NITIE Read more

    Ans. Here are some strategies that can help you prepare for GATE and ESE simultaneously. Compare the syllabus of GATE and ESE. Go through the previous years' questions of both. The technical portion of both examinations overlaps a lot. The major difference is question patterns and styles. Different types of questions are asked on the same topics. GATE tests aptitude for solving technical questions. While ESE puts more emphasis on technical details.  Figure out which subjects contribute more to which examinations.  If you have less time, start with GATE preparation. The topics can be covered easily and in less time. Once you are through GATE preparation, you can solve ESE questions without much difficulty.  Focus on GATE and ESE preparations only.  First, go through the syllabus thoroughly. Once you are done with the syllabus, go through your notes and solve previous years' questions. Solve test series, and review hard questions. Analyze the tests you give and work on your mistakes.  Read more

    Ans. GATE consists mostly of numerical questions. It tests the aptitude for solving questions in less time. BITS HD papers have 10-15 numerical questions usually. The numerical questions aren’t on the same level as GATE and are just formula-based problems. Usually, around 80-90% of BITS HD questions are theory oriented. You need to have a good grasp of your engineering subjects to score well in BITS HD. The questions can come from anywhere in the syllabus. BITS HD usually consists -  15 Mathematics questions (difficulty usually higher than GATE) 15 general English questions 70 Engineering discipline questions Also, note that BITS take admission based on GATE scores as well.  Read more

    Ans. The required GATE rank depends upon various parameters like  The engineering branch Company (PSU)  Number of vacancies for the stream People who are graduating in 3-4 years are lucky as both IOCL and ONGC are planning to recruit in bulk because of massive retirements in both the companies. The mechanical and chemical branches are expected to have the most vacancies. Candidates will be called in a 1:5 ratio and thus, interviews will be the major determining factor of your selection. If you are unable to showcase your knowledge and talent during the interview, even a single-digit rank cannot guarantee your admission. A minimum of 40% marks are required to pass the interview. So if you get a call for the interview, don’t let your rank discourage you or even make you overconfident.  Read more
