Ques. What do you prefer, the GATE or the IES?

● Top Answer By Keshav Jindal on 25 Feb 21

Ans. I would prefer GATE or IES because in GATE the ratio is 10:1 whereas in IES the ratio is 300:1. This makes IES a very tough competitive exam but in GATE it is easier to get good marks and rank higher as the paper is easy and less competitive compared to IES.  The IES exam is tougher than GATE because here a candidate has to excel both in academics and personality. In GATE the questions are concept based and it is easier to solve if all the concepts are clear. Also in the GATE exam, there are 65 questions and the time limit is 3 hours but in the IES exam there are 120 questions and the time limit is 2 hours. So you get less time to solve all the questions.  After qualifying for your GATE exam with good marks, you can apply to any of the big companies with higher packages and it also opens your gate to apply for PSU.   After qualifying for your IES exam, you will get a job as an assistant executive engineer and after 3-4 years of experience, you will get promoted to executive engineer post. Then after many years of experience of like 20+ years, you will get Chief Engineer posts.Read more

Ques. What is the pattern for the written test for M.Tech at IIT Gandhinagar?

● Top Answer By Kumar Shiwam on 24 Feb 21

Ans. The admission for M. Tech at IIT Gandhinagar is done on the basis of academic records, written test, personal interview, and valid GATE scores. Those students who have a good academic record along with good GATE scores are not supposed to appear in the written test and personal interview.  The pattern of the written test is as follows: 10 questions of General aptitude questions consisting of logical analytical and reasoning ability and engineering mathematics are asked. 15-20 questions are asked related to basic courses in various disciplines up to the third year of an undergraduate program. The total duration of the written test is 1 hour for 80 marks. A total of 40 marks for general aptitude and 40 for basic knowledge. There is a negative marking and very basic questions are asked in the test. For branch subjects, all questions are asked related to SOM, fluid mechanics, etc.  The reservation category will get relaxation in the cut-off marks as per the norms. You will also be entitled to and fro sleeper class train tickets for the shortest route from your hometown to the institute. If you pass the test then you will attend the interview on the same day.Read more

Ques. What are the best coaching centres for GATE and IES in Civil Engineering?

● Top Answer By Sabeer Chalana on 23 Feb 21

Ans. There are many coaching centers throughout the country for IES and GATE coaching. However, these 2 institutes enjoy a huge reputation and recognition at the national level due to their experienced faculty and their study material quality. Made Easy: It is one of the best in the field when it comes to GATE and IES coaching. They have the best faculty teaching the subjects for the students.  Their specialty lies in their high quality and concise presentation. One of my friends enrolled in the Delhi center weekend coaching program, which he claimed to be good. Their online test series is one of the best you can opt for. They are prepared keeping the present pattern in mind. The number of students enrolled is hefty and gives you a clear picture of the competition. Some criticize that their teaching lacks depth compared to other institutes. Their courses and tests require analytical knowledge and are more than enough to crack GATE/IES exams. IES Masters: This institute is one of the best in this field and has earned respect for its excellence and quality coaching within a short span of its inception. All the major subjects for all batches are handled by Mr. Kanchan Thakur who is the director of the institute. He has a brilliant command over all the subjects in Civil engineering. The study material of this institute is best and is even recommended for those who choose civil engineering as an optional subject in UPSC exams. One small setback is that other faculties than the director are not on par when compared with the faculties of Made Easy. For the GATE Online test series, you can opt for Made easy test series, and for the IES test series you can opt for IES Masters. If you plan to join made easy to enroll in Super Talent Batch which has all top faculties teaching in this batch. For Classroom coaching for civil engineering in GATE/IES, Super talent batch can be preferred if not then IES Masters. For Postal study course, one can opt for IES masters.Read more

Ques. Which will be a better career for ECE engineers, IBPS SO or PSU via the GATE?

● Top Answer By Vaishnavi Agrawal on 19 Feb 21

Ans. Some of my friends work in both the departments and based on their experience, I can answer this. If you look at the position of an IBPS SO, it's that of a specialist officer. You'd technically be a network administrator of all of the intra networks of the bank. You'd be a database administrator/database manager who would have the entire intra network of that particular bank under your supervision.  Now if you look at the PSU job, you'd be someone who would be responsible for sustaining the technicalities concerning PSU. Your enquiry on which one is better entirely is up to you and where your interest lies. While some might opt for GATE which concerns their core subjects entirely, others simply might find their area of interest in networking. So, decide for yourself and choose what suits you and not the rest.Read more

Ques. What is the difference between IES and GATE?

● Top Answer By Himani Arora on 17 Feb 21

Ans. GATE and IES, are very well known among graduate engineers. The IES exam is carried out annually by the Union Public Service Commission (UPSC) and the GATE exam is administered by Bangalore's Indian Institute of Science (IISc) or any of the seven IITs. Syllabus and paper pattern: The complete engineering syllabus is covered by the IES exam, while GATE covers a portion of this syllabus and some other topics useful for higher studies.  While GATE tests problem-solving ability, IES tests conceptual capability.  The IES exam paper contains questions of the objective and subjective type and a total of 4 papers, while the GATE exam paper only contains questions of the objective type and only 1 paper.  Only in the subjective paper, a calculator is allowed. Difficulty Level & Duration: It will be much more difficult to solve the questions you will face in GATE than in IES.  In a single problem, GATE questions require you to apply many concepts. For that, you should have good problem-solving skills.  While most of the questions asked in IES are direct formula or a single concept based. In GATE, in 3 hours, you have to solve 65 questions that are approximately 2.5 minutes per question.  On the other hand, you have 120 questions in 2 hours to solve in IES. So, 1 minute per question which means you get nearly 2.5 times more “time” per question in GATE. But the difficulty level compensates for it. Category of PSUs and Job Scope: UPSC conducts IES examination to recruit candidates under the Govt for different engineering departments (mechanical, electrical, civil, and E&T).  Around India, The departments you get through IES are Indian Railway Service of Engineers, Indian Railway Stores Service, Indian Ordnance Factories Service AWM/JTS., Central Electrical and Mechanical Engineering Service, Geological Survey of India Engineering Service Gr ‘A’, Central Engineering Service (Roads), Gr ‘A’, Central Water Engineering Service Gr ‘A’, Indian Defence Service of Engineers, Central Power Engineering Service Gr ‘B’ and so on. The GATE exam is organized for higher studies (, PH. Ed. etc) and for placements in PSUs and Govt. Organizations. From the above-mentioned factual information, the difference between the two should be clear. Rest all depends on your choice what you opt for.Read more
