A young man joins a Central Government office on a Monday. By Wednesday, the canteen conversation has already confused him.
One colleague says he came "on deputation." Another says she was "absorbed." A third grumbles that he is still "on probation" after a year and a half. The senior-most clerk, sipping his tea, says half the office got in through "direct recruitment" and the rest "by promotion."
Six different words. One office. And nobody stops to explain.
If you have ever felt lost in that alphabet soup, this guide is for you. We will walk through every legitimate way a person enters a Central Government post, how the trial period works, and where UPSC fits in — in plain language, the way a colleague would explain it over tea.

The Rulebook Behind Every Government Post
Recruitment Rules (RRs) are the official rulebook for a post — they decide how it is filled, who is eligible, and what qualifications and age limits apply. They are notified under the proviso to Article 309 of the Constitution, which makes them statutory: not internal office advice, but actual subordinate legislation a department must follow.
Think of an RR like the rulebook for a board game. Before anyone plays, the rules decide who can join, how a person moves from one square to the next, and what counts as a fair move. No department can invent a method on the spot.
Each RR has two parts: a notification (the substantive rules) and a schedule (the post-specific details — pay level, method of recruitment, eligibility, age, qualifications). For Group A and Group B posts, the administrative Ministry frames or amends these rules in consultation with the Department of Personnel and Training (DoPT), the Union Public Service Commission (UPSC), and the Law Ministry. For Group C posts, the department has more freedom but must still follow DoPT's model guidelines (DoPT FAQ, OM No. AB.14017/13/2013-Estt.(RR), dated 6 March 2013).
One small but important detail: qualifications in an RR are split into Essential and Desirable. Essential is the non-negotiable minimum. Desirable is the "nice to have" that helps you stand out — but its absence cannot disqualify you.
The Six Methods of Recruitment
There are exactly six recognised methods. Most posts use one or two of them. Here is what each one actually means.
Direct Recruitment
This is the open competition everyone pictures — exams, interviews, the whole works. Direct recruitment is open to all eligible candidates from outside, subject to the age, qualification and experience limits fixed in the Recruitment Rules. It is how most fresh entrants come in, whether through the SSC, UPSC, or a departmental exam.
Promotion
Promotion lifts an existing employee from a feeder grade to the next post in the hierarchy. The catch: the RR fixes a minimum qualifying service before you become eligible. And here is a point that trips many people up — only your regular service counts. Time spent in an ad hoc (stop-gap) capacity is not added when computing this qualifying service.
Deputation
On deputation, an officer from another Central department or a State / UT Government is borrowed for a fixed period, after which they return to their parent cadre. Deputation is especially useful for an isolated post — a one-of-a-kind position with no feeder grade — because filling it by direct recruitment would trap the person there with no path to grow.
Absorption
Absorption looks like deputation's cousin, but the two are not the same. Deputation is temporary; absorption is permanent. An officer who first arrives on deputation may later be permanently absorbed — but only if the RR specifically allows absorption, and only if the officer came on deputation from the Central or a State Government.
Re-employment
Armed Forces personnel retire young — often in their late 30s to early 50s, depending on rank — because the work is physically demanding. They are still energetic, still at the peak of their family responsibilities, and most need a second career. Re-employment is the route that brings ex-servicemen into civil posts. A dedicated framework — the Ex-Servicemen (Re-employment in Central Civil Services and Posts) Rules — governs their entry into Group C and MTS posts.
Short-Term Contract
This is a form of deputation aimed at specialists. Experts from universities, research bodies and public sector undertakings can be brought in on a short-term contract to fill teaching, research, scientific or technical posts that the regular cadre cannot easily supply.
