Sarah Murphy, a human development and leadership expert at Personio, a UK-based human resources software company, believes a negative first impression can hinder integration, erode trust, and even contribute to workplace loneliness.

Here are three common pitfalls to avoid on your first day:

Not connecting early

According to Murphy, many new hires focus too intensely on their professional skills, forgetting the equal importance of building relationships with colleagues. Passively waiting for others to initiate conversations can project a lack of engagement and create early isolation.

A simple solution is to proactively engage with colleagues. Strike up conversations during coffee breaks, offer greetings, or inquire about their work. These small gestures can make a significant difference and help you quickly become part of the team.

Misinterpreting the dress code

"Smart casual" is a familiar concept, but its interpretation varies across companies. Dressing too casually can make you appear unprofessional, while being overly formal in a relaxed office environment can create distance.

Dr. George Sik, a British psychologist and director of the consulting firm Eras, believes appropriate attire demonstrates social awareness, a valuable trait in any workplace.

He advises new employees to consult their hiring manager or observe the company's LinkedIn profile to understand the typical office attire.

Julian Nelson, a UK-based dress code expert, recommends choosing an outfit that makes you feel comfortable and confident. "Nothing detracts from a first impression more than fidgeting with your collar or limping in new shoes," Nelson said.

Trying too hard

Murphy observes that many new employees become preoccupied with proving their competence instead of taking time to listen, observe, and understand the team's culture.

"However eager they are to impress, they can fall into the trap of trying to prove too much, too soon," she said. Conversely, showing curiosity, asking questions, and being open can portray you as friendly and collaborative.

These initial connections can ease the stress of the first week and lay the foundation for long-term professional success.
