The Graduate Aptitude Test in Engineering (GATE) is an All-India examination administered and conducted in eight zones across the country by the GATE Committee comprising of Faculty members from IISc, Bangalore and other seven IIT’s on behalf of the National Coordinating Board, Department of Education, Ministry of Human Resources Development. The GATE score/rank is used for admissions to Post Graduate Programs (ME, M. Tech, MS, Direct Ph.D.) in institutes like IITs and IISc etc with financial assistance offered by MHRD. PSUs too use the GATE scores for recruiting candidates for various prestigious jobs with attractive remuneration.

In GATE examination, candidates can apply for only one of the 23 papers listed in the table given below. Candidates are expected to appear in a paper appropriate to the discipline of their qualifying degree. However, candidates are free to choose any paper according to their admission plan, keeping in mind the eligibility criteria of the institutions in which they wish to seek admission. For more details regarding the admission criteria in any particular institute, candidateso are advised to refer to the websites f that particular institute.

The Public Sector Undertakings of Indian Government, number more than 200 commercially functioning companies. The Public Sector Undertaking companies are better known by their shorter initial form of PSU. These undertakings are divided into two parts – state and central.

Public Sector Undertakings (PSUs) are government undertaking companies. These provide secure future and good money as these are less affected by the current recession. This sector provides a career for both technical and non-technical personnel.

The students from technical background can apply in technical service providing companies, i.e. BSNL, MTNL, SAIL, NHAI, NTPC, BHEL, ONGC, HPCL, IOCL, BPCL and many more. There are 252 PSUs in India. These PSUs recruit thousands of diploma and degree holding personnel in technical field. All these companies have their own recruiting procedures.

Some of these companies have competitive type examinations and others have technical written and interview rounds. The intimation for the examination is generally notified beforehand repeatedly in their websites and in all the leading daily newspapers.

Pay Structure of PSUs:

Varies according to the status of PSU (Maharatna, Navratna and Miniratna)

S.NO. Type of Companies Salary Structure
1 Maharatna 24900 - 50500
2 Navratna 20600 - 46500
3 Mini-Ratna 16400 - 40500


List of companies in the above three categories are given as

Major PSUs:

State-owned enterprises are called Public Sector Undertakings (PSU) or Public Sector Enterprises. These companies are owned by the union government of India, or one of the many state or territorial governments, or both. The company stock needs to be majority-owned by the government to be a Public Sector Undertaking. PSUs may be classified as Central Public Sector Enterprises (CPSEs), public sector banks (PSBs) or State Level Public Enterprises (SLPEs).

These Enterprises are further divided into-

1. MAHARATNA (Central Public Sector Enterprises)

2. NAVRATNA (Central Public Sector Enterprises)

3. MINIRATNA (Central Public Sector Enterprises)

Indian Engineering Services abbreviated as IES are the civil services that meet the technical and managerial functions of the Government of India. Like most countries, the Government of India recruits its civil servants and officials on the basis of merit, the middle management positions in the bureaucracy are filled through competitive exams. Large number of candidates takes these exams, competing for limited posts. IES officers are selected by the union government on the recommendations made by the Union Public Service Commission (UPSC). A combined three-stage competitive examination (comprising five tests), called the Engineering Services Examination (ESE) is conducted by the UPSC for recruitment to the Indian Engineering Services.

IES officers carry high respect and status in society and are able to manage activities in diverse areas. Government spending comprises more than 15 percent of India's GDP and given the extent of tasks and functions managed by the public sector, this extends to a fairly broad segment of the economy covering the railways, roads, defense,manufacturing, inspection, supply, construction, public works, power,telecommunications,etc.All appointments to the Group A services are made by the President of India

THE GATE COACH has been established in 1997 on the aegis of Kruttika Agencies Private limited by Mr. H.S.Teotia, an IIT Roorkie alumni. THE GATE COACH Journey from just a coaching Institute of IES(Indian engineering service), PSU(Public sector unit) and Gate(Graduate Aptitude Test in Engineering), to the most powerful brand in competitive education has been exhilarating.
THE GATE COACH is a temple of education with number of eminent faculty and proven track record. This is now pioneer institute in field of coaching of engineering subjects and has best success ratio in exams like Gate, IES & PSU.
Many of us have this question on mind, striving to improve ourselves to give the best of us in this competitive world. The world is changing at an extraordinary pace. And in today’s competitive landscape, there are survivals skills that young people need to master so that a measure of success can be assured.
If you are enthusiastic and ambitious, come and join hands with THE GATE COACH for the journey of success, the path is tiresome and enduring, the way is difficult, but if the approach is targeted, positive results are ensured.​
