What is BEL?
Bharat Electronics Limited (BEL) was set up at Bangalore, India, by the Government of India under the Ministry of  Defence in 1954 to meet the specialized electronic needs of the Indian defence services. Over the years, it has grown into a multi-product, multi-technology, multi-unit company serving the needs of customers in diverse fields in India and abroad . BEL is among an elite group of public sector undertakings which have been conferred the Navratna status by the Government of India. During 2008-09, BEL recorded a turnover of Rs.4624 crores.

                 This is a company which deals with a wide spectrum of products ranging from Radars to Solar based solutions. BEL goes much beyond the defence products they are famous for, they have made inroads into civilian products as well.Ranked among the top PSUs of the country, which has continuously made profits year after year.With massive infrastructure in the form of nine ISO certified manufacturing plants based on the state-of-the-art technology and many regional offices in all the major cities of the country as well as in New York and Singapore, BEL beckons the best brains of the country to be onboard - come , and be a part of us!!.

ELIGIBILITY - First class in Engineering Degree from AICTE approved Colleges / recognised Universities in Electronics / Electronics & Communication / Electronics & Telecommunication / Communication / Telecommunication / Mechanical / Computer Science / Computer Science and Engineering/Civil Engineering/Chemical Engineering. Candidates with AMIE / GIETE in the above specializations should have secured first class.
Age Limit
The maximum age limit for General candidates as on 01.04.2011 will be 25 years.
Upper age limit is relaxable by 5 years for SC/ST candidates and 3 years for OBC candidates.
In respect of PWD candidates upper age limit is relaxable by 5 years. In respect of PWD candidates belonging to SC/ST/OBC category, the age relaxation admissible will be over and above the relaxation admissible for candidates belonging to SC/ST/OBC.
.Relaxation will be extended as per Govt. guidelines in respect of Ex-Serviceman.
BEL Exam Pattern And Syllabus
The company is known to employ the best engineering talents of India.Almost every year in June/July BEL (Bharat Electronics Limited) conducts recruitment exam for graduate engineers (freshers) to recruit about 150 odd engineers.

BEL in its graduate engineer exam notification has not said much about the pattern of the written exam, except that the selection process would consist of a written test followed by interview.
So I had to search on the net for the pattern of written exam of previous years and I could find that the BEL written exam consist of a total 150 marks containing following two sections:
1.Aptitude section:consist of 30 questions each weighing 1 mark. Questions on passage comprehension, grammar, data interpretation & logical reasoning is asked.
2.Technical section:consist of 120 questions each weighing 1 mark. Subject specific (Electronics, Mechanical or Computer Science) questions are asked.You have to answer the 150 question, 150 marks paper in 2-n-half hour.There is negative marking of -0.25 for each wrong answer.and hence you should be cautious in making guesses.

There is a written test of 2.5 hours. The test consists of 30 questions based on aptitude maths and technical.. Apart from this there is a passage consisting of 3 questions. There are data interpretation questions, logical reasoning questions and questions on general knowledge.
The math questions are generally asked from topics like compound interest and height and distance. These questions can be really tricky.
The technical part consists of questions which aim to test the fundamental knowledge you have in subjects like solid state and electronics. Questions are there from Fourier transform, electrical, circuit theory, network theorems, filters, resistors connections etc.
There can be questions from control systems. Digital signal processing forms a major portion from where questions generally come. Some questions are from microprocessors.

following is the maths syllabus:
Probability: Conditional Probability; Mean, Median, Mode and Standard Deviation; Random Variables; Distributions; uniform, normal, exponential, Poisson, Binomial.
Set Theory & Algebra: Sets; Relations; Functions; Groups; Partial Orders; Lattice; Boolean Algebra.
Combinatorics: Permutations; Combinations; Counting; Summation; generating functions; recurrence relations; asymptotics.
Graph Theory: Connectivity; spanning trees; Cut vertices & edges; covering; matching; independent sets; Colouring; Planarity; Isomorphism.
Linear Algebra: Algebra of matrices, determinants, systems of linear equations, Eigen values and Eigen vectors.
Numerical Methods: LU decomposition for systems of linear equations; numerical solutions of non-linear algebraic equations by Secant, Bisection and Newton-Raphson Methods; Numerical integration by trapezoidal and Simpson’s rules.
Calculus: Limit, Continuity & differentiability, Mean value Theorems, Theorems of integral calculus, evaluation of definite & improper integrals, Partial derivatives, Total derivatives, maxima & minima.
this consists of 40% of the paper,rest g.k,aptitude.
