Learn How to Prepare for the Petrobras Competition with the Course That Approves the Most in the Country. Complete Guide with Tips, Study Plan, and the Best Preparation for the State-Owned Company.
The Petrobras 2025 Competition will be, according to internal projections of the state-owned company and estimates from public competition experts, the largest selection process in the company’s history. The expectation is that thousands of vacancies will be opened nationwide, covering high school, technical, and higher education levels, with salaries that can exceed R$ 20 thousand per month, as well as extensive corporate benefits.
The growth in demand occurs at a time of restructuring and energy transition for the company, which seeks qualified professionals to work in new industrial hubs, green hydrogen projects, refining, and biofuels.
Given this dimension, preparing in advance has become not just a competitive advantage but a necessity.
The New Era of Petrobras Competitions
The last public competition of Petrobras took place in 2023, organized by the Cesgranrio Foundation, and was marked by a record number of registrations: more than 300 thousand candidates competed for around 1,400 immediate vacancies and a reserve list.

In 2025, the scenario promises to be even larger. The strategic plan 2024–2028 of the state-owned company foresees increased staffing across all operational units and new research and production hubs, making the next announcement a landmark for engineers, technicians, and administrative professionals.
But the size of the opportunity is proportional to the level of demand. Petrobras is one of the public companies with the most technical and competitive competitions in the country, with exams that cover everything from logical reasoning to thermodynamics, industrial processes, and specific legislation. That’s why studying aimlessly, opening the announcement without knowing what to prioritize, is the mistake that eliminates 90% of candidates even before the exam.
The Secret Is Not to Study More, but to Study Right!
According to Professor William Arbelo, an engineer and public competition specialist, “most people fail not due to lack of effort, but due to lack of direction. The candidate gets lost trying to study everything and forgets what really appears on the test.”
It was based on this philosophy that the Concurseiro Zero1 was created, a course that has become a national reference for specific preparation for Petrobras and Transpetro. The method is structured around three pillars: material aimed at the bank, specialist teachers in competitions, and focused direction by professional emphasis.
While most courses offer generic packages, Zero1 works with specific tracks for each area (operation, mechanical maintenance, electrical, logistics, supplies, etc.), allowing for truly strategic study. The results were remarkable: the course that approved the most candidates in the last Petrobras competition, according to surveys from approved communities and independent rankings.

How to Prepare for the Petrobras Competition
Based on the experiences of approved candidates and the content of the Zero1 course, it is possible to outline a definitive preparation plan, divided into five stages that form the core of the Petrobras Competition Guide 2025.
Understand the Announcement and the Rules of the Game
Every candidate starting to study should begin by carefully reading the announcement—not just any announcement, but the last three Petrobras competitions. This is because each edition had a different bank (Cesgranrio, Cebraspe, and FunRio), with different question standards, weights, and criteria.
The specialists’ recommendation is:
- Read the 2023 announcement to understand the most recent exam format;
- Read the 2018 announcement, which follows the style of the bank expected for the next competition;
- And analyze the 2021 announcement if the goal is also to prepare for Transpetro, Petrobras’ subsidiary.
Understanding the announcement is more than just reading the schedule; it is deciphering the elimination criteria, tie-breaking, minimum scores by block, and quotas. This initial reading allows the candidate to define their emphasis (such as operation, instrumentation, maintenance, or logistics) and understand which contents really matter.
Analyze Previous Exams
The second step is to study the opponent. Yes, the Petrobras exam has a “own style”: the questions value interpretation, logical reasoning, and practical application of technical knowledge. Even if the candidate does not know how to solve all items, understanding how the subjects are covered changes the game.
This is what the Concurseiro Zero1 course does systematically: it provides exams from 2017, 2018, 2021, and 2023, with comments from engineering and technical professors in the area, allowing the student to perceive the pattern and adjust their study routine.
Organize a Realistic and Sustainable Routine
No Petrobras competition is won by those who study “whenever possible”. Constancy is required.
The ideal is to build a 20 to 30 hours per week routine, distributed over 1 to 2 hours a day during the week and 5 to 6 hours on weekends.
The Zero1 offers an interactive planner that the student fills in with their available hours. The system calculates free time, indicates which subjects to prioritize, and suggests automatic study and review blocks.
This type of structure is what transforms beginner candidates into elite competitors.
Plan the Study by Emphasis and Direct the Content
The central point of all study is to understand what to study for each position. Petrobras competitions are organized into emphasis blocks, and each of them has different technical content. Those who try to study everything end up wasting time and energy.
That’s why the Concurseiro Zero1 offers specific modules:
- Operation Technician: thermodynamics, industrial processes, instrumentation, and safety;
- Mechanical Maintenance: rotating machines, pumping systems, boiler making;
- Electrical: automation, electrical commands, inverters, industrial installations;
- Supplies and Logistics: materials management, inventory control, logistical processes.
Each track is designed by teachers with practical experience in the area, and the simulations follow exactly the difficulty standard of Petrobras.
Review and Simulate as If It Were the Real Exam
Studying without review is a waste of time. Every seven days, the candidate should review the studied content and apply weekly simulations to measure progress.
The preparatory course focused on the Petrobras competition already delivers automatic simulations with immediate correction and performance graphs by discipline, allowing tracking of the learning curve. This follow-up avoids the main mistake of those who study alone: thinking they are evolving when, in fact, they are just revisiting the same content without retaining anything.
The Advantage for Those Who Start Now
The biggest mistake candidates make is waiting for the announcement to come out. In large competitions like Petrobras’, those who start now are already 90% ahead of the competition.
This happens because, historically, the time between the publication of the announcement and the exam is short, around 60 to 90 days. In other words, when the announcement is published, those who are still organizing their routine will already be behind.
Studying in advance allows for understanding the bank, creating mental resilience for long exams, and consolidating content progressively. That’s why experts recommend that preparation should start in 2024, especially for those who intend to compete for technical positions, where the competition is tighter.
Choosing the Right Course Can Define Approval
Among the numerous courses available in the market, few are truly directed at the Petrobras competition. The preparatory course focused on the Petrobras competition stands out for gathering all the elements that define an efficient course:
- Updated material aimed at the organizing bank;
- Experienced teachers who have either been approved or work at Petrobras and Transpetro;
- Preparation directed for each emphasis and level of education;
- Complete planning with personalized schedules and simulations;
- Proven history of approvals in previous competitions of the state-owned company.
Unlike generic courses, Zero1 has built a practical and adaptable method, ideal for those who work and have little time to study. All content is available online and can be accessed at any time, with recorded classes and downloadable PDF materials ready for review.

More Than Studying: Learning to Play the Game
Competitions like Petrobras do not reward who knows the most, but who better understands the logic of the exam. And that is exactly what differentiates well-prepared candidates.
The Petrobras Competition Guide 2025 shows that the path is not to memorize formulas, but to master strategy and consistency. Those who follow the five steps: understand the announcement, analyze exams, organize the routine, plan the study, and review — will arrive ahead.
And if this path is taken with the support of a course specifically prepared for the competition, with teachers who already know the bank and with total focus on Petrobras content, the result tends to be the same as hundreds of students from Concurseiro Zero1: approval and stability in the largest state-owned company in the country.
