How PSU Selection Works: Routes, Panels and What the Interview Is Worth
This chapter gives you the map before you rehearse a single answer. It explains how candidates enter a public sector undertaking, what the 2015 Department of Public Enterprises order did to interviews for non-executive posts, and how to read the interview clause of a live notification. Every later chapter assumes the process taught here, so read it first and check each clause against the notice for the post you are actually applying for.

Two routes into a CPSE: GATE-linked and direct recruitment
A public sector undertaking (PSU) is an enterprise in which the government holds the controlling stake. The central government's PSUs that are companies are called Central Public Sector Enterprises (CPSEs). The Department of Public Enterprises (DPE) is the nodal department that oversees them. DPE does not set the interview process for an individual CPSE. Each company sets its own selection stages through its recruitment rules and its notice, so the same job title can follow a different process in two companies. A candidate who learns one company's pattern and assumes it applies to all of them has made the most common mistake in this area.
The first route is GATE-linked recruitment. The Graduate Aptitude Test in Engineering (GATE) is conducted jointly by the IISc and IITs on behalf of the National Coordination Board, and many CPSEs use GATE scores for engineering trainee posts. In this route the GATE score is often used to shortlist candidates, and the company then runs its own selection stage. That stage may be a group discussion, a personal interview (PI), both, or neither. The notice decides. A GATE score therefore does not tell you whether an interview is coming, and a candidate who has cleared GATE should not assume that a PI is certain.
The second route is direct recruitment, in which the company advertises posts itself and runs its own written test, its own interview, or both. Direct recruitment is common for management-trainee and executive posts, and it is where an interview is most likely to carry real marks. Notices in this route list the stages in order, and the order matters. A company that holds a written test in the morning and a PI later the same week needs a different plan from one that calls a shortlist for a PI alone. Read the stage sequence before you decide how to prepare.
| Feature | GATE-linked route | Direct recruitment route |
|---|---|---|
| Entry filter | GATE score in the notified paper, used as the notice sets | The company's own application and eligibility check |
| Written stage | May be none of the company's own, because the GATE score serves as the written stage | Usually a company-run written test, though the notice may omit it |
| Interview stage | Notice-dependent: a PI, a group discussion, or no interview | Notice-dependent; common at executive level |
| Where to check | The company notice that names the GATE paper and the shortlisting method | The company notice listing each stage, its marks and its order |
| Main planning risk | Assuming a GATE score guarantees a PI | Assuming the written test is the whole decision |
Executive and non-executive posts: where interviews still apply
CPSE posts are commonly grouped into executive and non-executive categories. Executive posts are management-cadre officer posts, typically entered at trainee or officer grades and promoted through a managerial pay structure. Non-executive posts are the operational, technical and supervisory posts below that cadre, including workmen and most staff who are not in the officer grades. The exact boundary is set by each company's recruitment and pay rules, so check the notice for the grade name rather than trusting the job title, which can be misleading.
The distinction matters because the central rules on interviews were framed around it. The 2015 changes removed most interviews for non-executive posts. Interviews have remained common in many CPSE notices for executive posts, but that is an observed pattern, not a general rule. A candidate who sees 'Management Trainee' in a notice should check the stage list, while a candidate who sees 'Technician' should check whether an interview is listed at all rather than assume one.
For preparation, the practical test is simple. If the notice lists a personal interview, a group discussion or a skill test as a selection stage, you are in the interview-stage pool for that post, and you should prepare for it. If the notice lists only a written test and document verification, do not build an interview plan for that post, even if the company is well known. Read the selection-process heading in full, and do not rely on a forum summary, because forums mix notices from different companies and different years.
What the 2015 DPE order changed
On 14 December 2015 the Department of Public Enterprises issued an office memorandum, file number DPE-GM-01/0001/2015-GM-FTS-4857, on the discontinuation of interviews for recruitment to non-executive posts in CPSEs. It followed a decision of the Department of Personnel and Training (DoPT) to end interviews for Group C and Group D posts and for non-gazetted Group B posts in the central government. The memorandum asked administrative ministries to direct their CPSEs to amend recruitment rules where those rules still required interviews for non-executive posts.
The DoPT order of 29 December 2015 (order number 39020/01/2013-Estt(B)) confirmed the change for government posts and set 31 December 2015 as the date by which the changeover had to be completed. Secondary copies describe junior-level recruitment proceeding without interviews from 1 January 2016; that start date is not stated in the sources checked, so treat it as the planning date rather than a quoted rule. A secondary copy's OCR text also says the rule reaches public sector undertakings, but the scanned original was not read in full, so this book does not rely on that reading. The DPE memorandum is the instrument that applied this change to non-executive recruitment in CPSEs, and the DoPT order of 29 December 2015 is the parent decision it follows; the DoPT order is cited here for the government-post rule.
The memorandum did not ban every interview in every CPSE. It allows an interview where the interview is considered essential for a post, but only if the CPSE obtains clearance from its administrative ministry first. Alternatively, the CPSE may adopt another way of assessing the skill in consultation with that ministry. The condition is clearance or an approved alternative, not the company's own preference. For a candidate, this means that an interview surviving in a non-executive notice is usually explained in the notice or its selection criteria. If you cannot find that explanation, treat the stage as uncertain and ask the company in writing before you spend weeks on preparation.
Two limits follow. First, the memorandum concerns non-executive posts, so it does not abolish interviews for executive posts. Second, later orders may update the position, and secondary summaries are not a substitute for the original text. The original DPE memorandum is published on the DPE website and reproduced in secondary sources. Re-check the original before quoting its wording in an answer or in an exam.
Reading the interview clause in a notification
Most notices carry three clauses that decide what you face. The selection-process clause lists the stages in order. The weightage clause states how each stage's marks are combined into a final score. The document-verification clause lists the documents to carry and the reporting rules. Read all three before you plan. A missing clause is also information. If a notice says nothing about interview marks, you cannot assume that interview marks exist, and you should not assume that they carry any fixed weight.
Look for the words that create obligations. The phrase 'interview marks will be added to the written marks for preparing the merit list' tells you the interview adds to the total and can change the rank. The phrase 'the interview shall be qualifying in nature' usually means you must reach a minimum mark but the score does not count toward the merit total. The words 'may be called' or 'as deemed fit' make a stage discretionary. A distinction between these wordings changes the whole plan, so it is the first thing to check in any notice that mentions an interview.
The table below lists the clauses to check and what each one changes for a candidate. Work through it for every notice before deciding how much time to give to interview preparation.
| Clause to check | What to look for | Why it matters |
|---|---|---|
| Stage list | Written test, group discussion, PI, skill test, document check, medical | Shows whether a PI exists at all for the post |
| Weightage | Marks or percentage for each stage, and whether stages are added or normalised | Decides how far one interview can move your rank |
| Qualifying or merit | Whether the interview is a minimum-mark hurdle only or counts in the merit total | Decides whether a strong interview can improve your rank |
| Shortlisting ratio | Number of candidates called for the interview for each post | Shows the pressure at this stage |
| Document verification | Documents listed, original and photocopy rules, date and place | A missing document can end candidacy |
| Tie-break | The rule applied when merit scores are equal | Often decides close ranks |
Composite scores: worked arithmetic with hypothetical weights
A notice that combines stages with weights must first bring each stage to a common scale, because the raw totals differ. The method has three steps. Divide each stage score by that stage's maximum, multiply by 100 to get a percentage, multiply by the stage's weight, and add the results. In symbols, the composite is the weight of the written stage times the written percentage, plus the weight of the interview times the interview percentage, with the two weights summing to 1.
Consider a hypothetical clause, which is not taken from any real notice: the written test is out of 100 and carries 75 per cent weight, and the personal interview is out of 50 and carries 25 per cent weight. A candidate who scores 42 in the interview has 84 per cent of the interview marks. Multiplying the raw 42 by 0.25 gives 10.5, which is meaningless because it is not a percentage. The correct contribution is 84 multiplied by 0.25, which is 21 composite points. The arithmetic only works when each stage is first expressed as a percentage of its own maximum.
The weights also cap what each stage can contribute. Under the hypothetical 75:25 split, the interview can contribute at most 25 composite points, whatever its raw marks. The written test's contribution is capped at 75. A candidate with a written percentage of 60 therefore has a maximum of 45 from the written stage and needs the interview to supply the rest. This is the most useful way to read a weightage clause: work backward from the target you need, and find out how much the interview must deliver. A target that the interview cannot reach is a sign that the written stage needs more attention, not the interview.
Rank effects matter more than totals. Two candidates may be close on the written test and far apart on the interview, or the reverse. The effect of the interview depends on the weights. When the interview weight is small, a large interview gap moves the composite only a little. When the weights are closer together, the same gap can reverse the order. Test each case with the arithmetic rather than by intuition, because the two cases are easy to confuse under time pressure.
