ABB Recruitment for Freshers: Selection Process Guide
ABB campus process: 110-question online test, GD, technical and HR interview. Full syllabus and prep tips for ECE, EEE, Instrumentation, and Mechanical freshers.
ABB’s campus selection runs four rounds (online test, group discussion, technical interview, and HR), and the written test is built for core engineering branches, not just CSE.
That distinction matters. ABB is an electrification and automation company, not an IT services firm. Its four business areas (Electrification, Motion, Robotics and Discrete Automation, and Process Automation) mean the freshers it wants are EEE and Instrumentation graduates who understand switchgear and drives, ECE graduates who can speak to control systems, and Mechanical engineers who can work inside a plant environment. The online test reflects this. So does the technical interview.
This guide covers every stage with the specifics you need to prepare.
About ABB
ABB, short for ASEA Brown Boveri, was formed in 1988 through the merger of ASEA (Sweden) and Brown Boveri (Switzerland). It is headquartered in Zurich and operates in roughly 100 countries. The company’s India operations span manufacturing plants in Vadodara, Nashik, Bengaluru, and Faridabad, covering the full range of ABB’s global product lines: power distribution equipment, variable speed drives, motors, industrial robots, and building and process automation systems.
ABB’s four business areas define what it looks for in campus hires:
| Business Area | What it builds | Engineering streams it hires |
|---|---|---|
| Electrification | Switchgear, circuit breakers, EV charging, solar inverters | EEE, ECE, Instrumentation |
| Motion | Motors, drives, generators, traction systems | EEE, ECE, Mechanical |
| Robotics and Discrete Automation | Industrial robots, machine vision, PLCs | ECE, Mechanical, CSE |
| Process Automation | Control systems for oil, gas, chemicals, pulp | Instrumentation, Chemical, EEE |
Graduate Engineer Trainees and Project Trainees are the typical fresher entry points. The specific role and business area you target will shape which parts of the technical interview dominate (more on that in the interview section below).
Eligibility Criteria
| Criterion | Requirement |
|---|---|
| Degree | BE / B.Tech or ME / M.Tech from an approved university |
| Eligible branches | ECE, EEE, Instrumentation and Control, Mechanical (and CSE / IT for select roles) |
| Academic percentage | Minimum 60% in Class X, XII, and graduation individually |
| Experience | 0–2 years (entry-level / fresher category) |
| Active backlogs | Not permitted at the time of application |
A few points not obvious from the table:
- The academic threshold applies stage by stage (Class X, XII, and graduation individually), not just to the final UG aggregate.
- A student with 59% in Class XII and 72% in graduation falls short, even with a strong overall profile.
- ABB’s recruiting division may narrow or expand the branch list for a given drive; confirm with your college placement cell.
Selection Process Overview
| Stage | Format | Primary filter |
|---|---|---|
| 1. Online Test | 110 questions, 110 minutes | Aptitude and technical knowledge |
| 2. Group Discussion | Topic-based discussion, 5-minute prep | Communication and structured reasoning |
| 3. Technical Interview | 1–2 rounds, panel of senior engineers | Domain depth and problem-solving |
| 4. HR Interview | 1 round | Cultural fit and communication skills |
All four stages are typically completed across one or two consecutive days during a campus drive.
Online Test: Pattern and Syllabus
The written test is the primary elimination round. Based on past drives, it has 110 questions across 110 minutes, split into two sections (ABB test pattern reference, HireBullseye):
Aptitude Section (50 questions, 50 minutes)
Three sub-sections:
- Verbal Ability: Error in sentences, sentence rearrangement, reading passages, jumbled sentences
- Analytical Reasoning: Coding-decoding, puzzles, blood relations, pie charts, tables, syllogisms
- Attention to Detail: Pattern-matching and identifying similar figures or data pairs
Difficulty is moderate. There is no premium on speed: the time allocation is one minute per question. Accuracy matters more than rushing.
Technical Section (60 questions, 60 minutes)
This section is where ABB’s core-engineering focus becomes visible. Topics covered:
- Switchgears and circuit breakers
- Electrical and electronics fundamentals (circuits, machines, power systems)
- RDBMS and database administration basics
- UNIX commands and operating system concepts
- OS and networking fundamentals
The software topics (RDBMS, UNIX, OS) may seem out of place for an EEE or Instrumentation student. They reflect the reality that ABB’s control systems, SCADA platforms, and drive firmware all run on software stacks; the company expects engineers to have basic software literacy even in hardware-first roles.
The level overall is moderate to tough. Only candidates who clear the written test move to the next round.
Preparation Tips
For the aptitude section, HirePro’s online test platform hosts company-style timed mock tests useful for calibrating speed. For the technical section, revise core subject textbooks (Electrical Machines, Power Systems, Control Systems, Digital Electronics) alongside basic DBMS and OS; most CS fundamentals textbooks cover RDBMS and UNIX at the right depth for this test.
Texas Instruments’ campus test is a useful comparison: TI also runs a profile-based technical test for ECE and EEE students, and the core-subject preparation overlaps significantly with ABB’s technical section.
Technical Interview and HR Round
Group Discussion
The GD typically uses industry-trend or ethics-based topics: sustainability, energy transition, manufacturing automation, business ethics. The format is straightforward: candidates get 5 minutes to organise their thoughts, then the discussion begins. Based on past drives, roughly half of GD participants are shortlisted. State your position in the first two or three contributions rather than waiting for an opening; waiting through a full GD without speaking substantively is the most common reason for elimination at this stage.
Technical Interview
The panel is usually drawn from senior ABB engineers with substantial project experience. The format has two parts:
- Candidates identify 2–3 preferred technical domains for deeper discussion
- The interviewer probes those domains with conceptual questions and real-world application scenarios
Commonly Asked Technical Questions
- Why is the star-delta starter preferred for induction motors?
- Explain the working of a circuit breaker and when each type is used.
- What are the advantages of AC systems over DC for power transmission?
- Explain cache memory and its performance trade-offs.
- What is a PLC and how does it differ from a microcontroller in an industrial setting?
- Describe a DBMS transaction and explain ACID properties.
The last two questions (PLC and DBMS) come up even for EEE and Instrumentation candidates because ABB’s products sit at the intersection of hardware and software. Knowing the basics of both gives a real edge.
HR Interview
The HR round covers cultural fit, communication, and motivation. Typical questions:
- Walk me through your background and why you chose your branch.
- How do you manage pressure in a team setting?
- Why ABB specifically, and which business area interests you?
For the last question, a specific answer: “Electrification, because I want to work on distribution automation in India’s grid modernisation” always lands better than “I like ABB’s global presence.”
How to Apply
On-Campus
Most fresher hiring happens through campus drives coordinated with college placement cells. Final-year students should register with their placement cell and track announcements for ABB-specific drives. Shortlisting before an on-campus drive is usually based on academic percentage and branch eligibility.
Off-Campus
ABB lists roles year-round on its India careers page. Steps to apply:
- Visit careers.abb/india/en and filter by “Entry Level” or “Graduate”
- Set job alerts for relevant cities (Bengaluru, Vadodara, Nashik, Hyderabad)
- Upload a resume with academic percentage and stream clearly stated
- Track application status through the portal
Reliance’s recruitment process follows a comparable structure for core engineering branches. The documents checklist and application flow are similar.
Documents to Carry on Interview Day
- Updated resume (two copies)
- Three to four passport-size photographs
- Academic mark sheets for Class X, XII, and graduation
- A valid government-issued ID (Aadhaar, PAN, or passport)
- Internship or project certificates, if any
- Printout of your online application confirmation
ABB’s online test includes RDBMS, UNIX, and OS questions that catch many core-branch students off guard. Most EEE and Instrumentation students don’t practise those. That software layer is not just a test curiosity: it is where data from drives, sensors, and control systems actually gets processed. If you want to build that software and AI fluency alongside your core-engineering preparation, TinkerLLM is a ₹299 starting point.

Frequently asked questions
What branches are eligible for ABB campus recruitment in India?
ABB's core campus drives are open to ECE, EEE, Instrumentation and Control, and Mechanical Engineering graduates. Some software and IT-adjacent roles additionally accept CSE and IT branches. Eligibility can vary by drive and by the specific business division recruiting — always confirm with your college placement cell before applying.
Is there negative marking in the ABB online test?
ABB's standard test pattern does not publicly specify negative marking. Based on past drive accounts, selective answering is still advisable on sections where you are uncertain — skipping a question costs nothing while a wrong answer may carry a penalty. Confirm the marking scheme with your college placement cell once the specific drive details are announced.
What technical topics are covered in the ABB written exam for core engineering students?
The 60-question technical section covers switchgears, circuit breakers, electrical and electronics fundamentals, RDBMS, database administration basics, UNIX, and OS and networking concepts. The mix reflects ABB's product portfolio: both core electrical hardware and the software layers that monitor and control those systems.
How is the group discussion round conducted at ABB?
Candidates are given a topic — typically an industry trend, business ethics question, or sustainability issue — and 5 minutes to think before the discussion begins. ABB shortlists roughly half the GD participants, so stating a clear position early and backing it with structured reasoning matters more than speaking the most.
Can I apply off-campus for ABB if my college does not have a placement drive?
Yes. ABB lists open positions year-round at careers.abb/india/en. You can filter by entry-level and graduate roles, set up job alerts, and apply directly. Off-campus shortlisting is based on resume screening, so a well-structured CV with your academic percentage and branch clearly stated is the first filter.
What documents should I carry for ABB campus interview day?
Carry an updated resume (two copies), three to four passport-size photographs, academic mark sheets for Class X, XII, and graduation, a valid government-issued ID (Aadhaar, PAN, or passport), and any internship or project certificates. Some drives also require a printout of your online application confirmation.
