Safe and Secure Jobs for freshers in State, Central Government and Public sectors

No comments
secure ece jobs

I got so many mails about different jobs for fresher's in state and central government, Employment in the private sector is considered financially more attractive. But most youngsters and their parents are not aware that employment in government and public sectors is more accessible to all in a constitutionally mandated non-discriminatory framework.  Even if they are aware of these opportunities, they do not have ready and convenient access to the eligibility criteria and entrance procedures and requirements for seeking employment opportunities in government and public sector organizations.

Recently I found a good eBook which covers all the information's about state and central government opportunities. In that book they said about the different opportunities available to all field of education like engineering,commerce,medicine etc.. and also they cover what are the entrance exams we need to write to enter in to those fields, they clearly explain each and every thing.
It’s a really good book which gives a lot of information to young graduates , I am sharing that book(you can download in pdf format below) to all the graduates and I hope it will helpful to all jobseekers.

sail syllabus for eceSAIL OCTT recruitment follows several steps of short listing process which comprises written exam, interview and medical examination.After successfully applying for this job everyone will start their preparation for first process i.e written test, here I want to tell model exam pattern and syllabus for OCTT.

Actually there is no particular syllabus for this exam and the syllabus will changing for every year so,there is a lot of confusion in applicants what to study?.Here I had to provide the previous year exam pattern for electronics.

This is not the exact syllabus given by any SAIL Team, this might be change I am just giving idea about the exam pattern and syllabus based on previous year exams.


This Test will be conducted for duration of 145 minutes and objective type questions will be asked for 250 marks.

The paper pattern consists of two sections 1. Technical   2. General section


1. Technical section: In this they will ask questions from your respective branches,for electronics they will mostly ask from Basic electronics,Analog electronics,Digital electronics,Communication(analog and digital),microprocessor,control systems And there is a chance to ask some questions (may be 2-5 questions) based on electrical subjects too.


2. General Sections:

    a. General Awareness

    b. Quantitative Aptitude

    c. General English

    d. Reasoning

Fill your wallet while learning in a college-make money

No comments

making money onlineMaking money while in college is not very common in INDIA as it is abroad and spending money is a natural ability,but earning it while in college is an alien concept and skill that need to be acquired.The commitment of a modern student to always improve his/her standard of living and the hopes of managing with the funding by parents becomes unimaginable.Thus,we are staring at the cruel fate of the need to apply our knowledge and skill to earn money.Now we are ready to cut-short our chatting or gaming hours a bit and spend that time in making money to fill your wallet.


when you type “Making money online” in Google search millions of pages will open but we don’t know which we have to trust here I am telling some ideas which I and millions of peoples trusted and filling their wallets while studying.

For those of you with time on your hands and the drive to make an extra buck,freelancing is a great way to fatten your wallet.

Some freelancing jobs:

1. Article Writing : If you have good writing skills this opportunity is good to create an articles. A 300 word article can fetch you as much as Rs. 250.

2.Computer programming : A large number of companies are in need of freelancer programmers for projects with PHP,JAVA,PERL,ASP etc…, they will pay you Rs 4000 –Rs 6000 for an hour work.

3.Graphic designs : Logo designs,T-Shirt design you can earn as much as Rs. 6000

4.Photo editing : If you have good knowledge in Photoshop you can undertake photo editing projects.

5.Photography : If you have a camera and photography is an hobby then you can make money by selling the photos.

6.Proofreading : Here content will provide to you and your job will be to check for errors.


Websites proving the freelancer works are: www.freelancer.in , www.fiverr.com , www.rewarder.com .

Important non technical subjects for ece Must read to get a job

1 comment

non technical subjectsHi! Today I am going to tell important subjects that every student must learn in his graduation other than technical subjects to get a job quickly.Now a days most of the students are some what good in technical,even though they are good in technical also they are not success to get a job,Why because most of the companies conduct written exam before conducting interviews,if you are good in only technical wont give success in written exam that means the written exam consists of other than technical questions. So,most of the students was unable to clear this level.Now I will tell you what are those nontechnical subjects.

1. Aptitude and Reasoning:

          Almost every companies in private sector(software or a core company) or a government companies ask 30-40% questions from this areas.This test is useful to test your logical thinking and performance.

2. C language and computer organisation:

          Most of the ECE students don’t like C in their graduation,I am also one of the person who don’t like C language,But its necessary to get a job. Most of the Private sector companies its may be software or core company will ask 20-30% questions in written exams. So,we can’t escape from this subject.The Computer Organisation is one which mainly asked by some government companies like DRDO,ISRO,BARC etc…

3. English :

         I know that you are good in English, Most of the students can speak English well but for the exam point of view they made mistakes, because in exam we need good in vocabulary, sentence corrections,we should know perfect meaning of the words etc.. Most of the government companies ask 10-20% questions from English and all these questions are very easy and mostly these questions are asked in the level of 10th class what we have already learnt.

4. General studies and General knowledge:

        This is the one of the major area to qualify written exam of any government/PSU exam. Mostly they will ask 20-30% questions from this area. One who manage all these subjects parallel to their technical subjects will get success soon.

I will discuss about  how to study all these non technical subjects in my future articles……Bookmark or subscribe your email for further updates

Now to get in to these post first you must Qualify written Exam and Interview, Written Exam consists of  five papers and the exam will conduct on 3 days.
paper-1 General studies
Paper-2 Objective technical(6 subjects)
Paper-3 Objective technical(6 subjects)
Paper-4 Descriptive technical(6 subjects)
Paper-5 Descriptive Technical(6 subjects)
Each paper consists of 200 marks and the interview is of 200 marks totally 1200 marks.we have to clear all these rounds to enter in to government posts mentioned above and It is easy to clear IES if you have a good preparation plan and you must prepare at least 6months,So we should plan from now onwards ,if you need any help contact us. I will post syllabus and books for IES on later.

A mini robot powered by your smart phone TED video

No comments
Your smartphone may feel like a friend -- but a true friend would give you a smile once in a while. At TED2013, Keller Rinaudo demos Romo, the smartphone-powered mini robot who can motor along with you on a walk, slide you a cup of coffee across the table, and react to you with programmable expressions.

Keller Rinaudo is the co-founder and CEO of Romotive -- makers of the small, covetable robot, Romo.   Full bio in TED »
