Absolutely Do Not Do This in Your First 90 Days at a New Job

New job? Don't rush to impress! Learn how to navigate your first 90 days to avoid pitfalls and build a successful career.

The first 90 days in a new job are not the time for demonstrating initiatives, quick wins, or attempting to impress management. This approach, often promoted in onboarding programs, can lead to unforeseen conflicts and long-term stagnation. The author's experience, spanning 20 years in IT and over 10 years in leadership positions, shows that employees who hold strong positions after a year focus their first three months on an invisible but critically important task—building an organizational map.

Three Layers of the Company Map

This map consists of three key layers:

1. The Real Power Structure

The formal organizational structure often differs from the real one. A new employee only sees the official hierarchy, but real power may belong to people in different positions. For example, a CTO may formally lead, but actual decisions might be made by a long-standing architect with influence on the board. Similarly, product advancement might be driven not by a Product Director, but by a Senior Product Owner with a direct line to senior management. In HR, real hiring decisions might depend on a specific HR manager who has strong ties with lead recruiters.

Gathering this information involves observation: who is listened to in meetings, who can interrupt without consequence, who has direct access to leadership, and who is approached for specific problem-solving. The goal within the first 90 days is to understand the real influence of the three to five key individuals you will be working with. An initiative directed at the wrong person may go unanswered, while approaching the right person can resolve an issue in a single day.

2. Boundaries and Taboos

Every company has unspoken topics whose discussion can provoke a disproportionately negative reaction. This is often due to past conflicts, grievances, or failures. A new employee, by accidentally touching upon such a "taboo," may encounter misunderstanding and problems.

Examples of such taboos include:

  • Reasons for reorganization or team disbandment if the decision was controversial.
  • Criticism of past product launch failures, especially if current employees were involved.
  • Mentioning specific vendors with whom the company has poor relations.

This information is conveyed verbally and is not available to newcomers. Identifying these taboos requires careful observation: how people react to certain topics, which phrases cause abrupt silence. Any comparison to previous work experience without understanding these nuances can lead to conflict.

3. Working and Mimic Processes

Every company has formal processes: planning, retrospectives, code reviews, technical committees, etc. However, not all of them function equally. Some processes are real decision-making mechanisms, while others are merely formalities.

It is critically important to understand this difference within the first 90 days. Planning can be either a real decision-making process or a ritual for voicing decisions already made behind closed doors. Retrospectives can serve for genuine reflection or be a formal hour where only positive aspects are discussed. Technical committees can genuinely define architecture or merely approve decisions made in advance by key individuals.

An employee who does not understand this difference risks wasting time preparing for "theatrical" meetings or missing opportunities to influence real processes by not preparing for them adequately. The task within the first 90 days is to test key processes, assessing where real decision-making occurs and where it is merely imitation. This will allow you to determine which processes are worth investing effort in and where formal participation is sufficient.

Strategy for the First 90 Days

Activity in the first 90 days without understanding the company's internal map is a "shot in the dark." Even a brilliant idea, proposed to the wrong person or within a non-functional process, will not be implemented and can create enemies. Externally, such behavior appears dull: completing assigned tasks, listening attentively in meetings, asking clarifying questions without judgmental opinions, and refraining from criticizing existing processes or suggesting their overhaul.

Internally, however, active information gathering is taking place: every meeting, every conversation, every comment on a neighboring team's code review is data for building a model of the organization. By the end of the 90 days, such an employee will have developed a comprehensive model, allowing them to act consciously.

Managers observing this behavior might consider the employee "normal, but not yet shining." This is the correct impression. Those who "shine" in the first few months have often already stepped on "mines" and will be dealing with the consequences. An employee who gathers information accumulates capital for a future breakthrough.

Managing Manager Expectations

Tasks assigned by a manager should be executed excellently – this is visible activity. It is better to postpone initiatives and strategic proposals until the fourth or fifth month. By this time, the employee will have formed a map that allows them to propose a solution that will be implemented through the right processes and with the right people. An initiative proposed in the second week might create enemies and not be accepted. The same initiative in the fifth month, fitting into the right structure, will become the first major success.

In the case of a strict 90-day probationary period, demonstrating results should consist of excellent execution of assigned tasks and active participation in meetings by asking intelligent questions. Companies expecting a revolution from a newcomer on probation have a poor hiring culture. A good company, in the first 90 days, tests the employee's ability to work within the existing context, rather than redesigning it.

Key Question for a Manager

In the first week of a new job, instead of asking about 90-day goals, ask your manager: "Is there anything I should absolutely avoid doing in the first 3 months?" This question can reveal two or three specific mistakes that previous new hires made, providing a valuable part of the organizational map for free.

Often, people who didn't pass their probation period or struggled through it were active in the first 30-60 days, got into unforeseen conflicts, and then spent time resolving them, despite their technical competence. The problem lay in "acting in the dark" with high activity.

Conclusion

Those who do nothing outwardly in the first 90 days but actively map the organization find themselves in the strongest position after a year. This invisible work allows them to act consciously, avoiding pitfalls and conflicts. The first 90 days are a unique window for information gathering that should be used to build a foundation for the next 3-5 years, rather than for attempts to impress others. Observing the real power structure, identifying taboos, and understanding work processes will allow one to reach a position after a year that may seem inexplicable to more "active" colleagues.

The Main Task of the First 90 Days

In the first 90 days of a new job, avoid excessive initiative. Instead, focus on gathering information about the real power structure, boundaries and taboos, and which processes actually work versus those that are merely simulated. This "company map" will help you avoid mistakes and act effectively.

  • The first 90 days are not the time for initiatives and quick wins.
  • The main task is to assemble a "company map": understand the real power structure, boundaries and taboos, and actual processes.
  • Ignoring this task leads to acting blindly and potential conflicts.
  • The map consists of three layers: the real power structure, boundaries and taboos, and actual processes.

Layer 1: The Real Power Structure

The first layer of the map is the real power structure. It's important to understand who actually makes decisions, not just to follow the formal hierarchy. Observe who is listened to in meetings, who has weight and influence, even if their position is formally lower.

  • The formal company structure differs from the real one.
  • Decisions are often made by people who do not hold high formal positions (e.g., architects, lead product owners, experienced HR managers).
  • Observe who is listened to, who interrupts, who can call management directly.
  • The goal is to understand which key people have real weight and who holds a formal position.

Layer 2: Boundaries and Taboos

The second layer of the map is boundaries and taboos. In every company, there are topics that are not customary to discuss due to past conflicts or failures. Carelessly touching upon such topics can cause a disproportionate reaction.

  • There are informal taboos and topics that are not discussed.
  • Violating taboos can lead to a disproportionate negative reaction.
  • Examples of taboos: reasons for past reorganization, unsuccessful product launches, bad vendor relationships.
  • Identify taboos through careful observation and colleagues' reactions to certain topics.

Layer 3: Real Processes

The third layer of the map represents real processes. It's important to distinguish between formal processes (planning, retrospectives, tech committees) and those that actually work and where decisions are made. Misunderstanding this leads to wasted time.

  • Formal processes (planning, retros, code reviews) can differ from real ones.
  • Some processes might be rituals, with decisions made behind closed doors.
  • Mid-level engineers who don't understand the difference waste time in unsuitable meetings or don't prepare for important ones.
  • Test key processes to understand where real decisions are made.

Correct Behavior in the First 90 Days

Externally, behavior in the first 90 days should be restrained: complete assigned tasks, listen, ask clarifying questions. Internally, active information gathering is taking place. This lays the foundation for future successful initiatives.

  • External behavior should be calm: task completion, listening, clarifying questions.
  • Avoid heroic initiatives, criticism, and suggestions for redoing the architecture.
  • Internally, active information gathering occurs at every meeting and in every conversation.
  • By the end of 90 days, a comprehensive model of the company is formed, allowing for conscious action.

Probationary Period and Manager's Expectations

If you have a tough probationary period, focus on excellent execution of assigned tasks. A company with a good hiring culture expects adaptation from a newcomer, not revolutions. Ask your manager what you should definitely not do.

  • Demonstrate results within the scope of assigned tasks.
  • A company with a good hiring culture tests for adaptation, not for context revision.
  • Ask your manager: 'What should I definitely not do in the first 3 months?'
  • The manager's answer will provide valuable information about hidden taboos and pitfalls.

Conclusion: Mapping as the Foundation for Success

The main work in the first 90 days is to collect an invisible map of the organization. This gives you an advantage over colleagues who are trying to make an impression. Use this time to gather information that will be useful for years to come.

  • The main work in the first 90 days is to collect a map of the organization that is invisible from the outside.
  • Those who collect the map find themselves in a strong position after a year.
  • The first 90 days are the only window for asking questions without the pressure of initiatives.
  • Use this time to gather information that will be useful in the next 3-5 years.
