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

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 Exam pattern and Syllabus for Diploma ece Operator cum Technician Trainee

SAIL 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
