one-on-one

one-on-one — A private meeting between two people, typically a manager and an employee, to discuss work progress, feedback, or personal development.

In simple English

A one-on-one is a scheduled or impromptu meeting that involves only two people. In tech companies, one-on-ones are most commonly held between managers and their direct reports on a regular basis (weekly or bi-weekly). These meetings serve multiple purposes: sharing feedback, discussing career goals, addressing concerns, and building relationships. Unlike team meetings or standups, a one-on-one is private and focused on the individual. The term is also used more broadly to describe any two-person meeting, such as mentorship sessions, performance reviews, or informal check-ins between colleagues. The word emphasizes the personal, one-to-one nature of the interaction.

How to say it: Often written "1:1" and said "one-on-one".

Real examples(3)

  • manager scheduling

    "I blocked off 30 minutes every Friday afternoon for one-on-ones with each team member."

  • employee communication

    "During our one-on-one, I mentioned that I want to learn more about system architecture."

  • mentorship

    "The senior engineer suggested a one-on-one to help me prepare for the technical interview."

More mistakes(2)

Handle with care. One-on-one is a noun describing a meeting format, not a verb. Do not use it as 'we need to one-on-one this issue' — instead say 'we need a one-on-one about this issue'.

  • ✕Let us one-on-one this problem.
    ✓Let's schedule a one-on-one to address this problem.

    Again, one-on-one cannot be used as a verb. Pair it with 'have', 'schedule', or 'do'.

  • ✕This is a one-on-one meeting with three people.
    ✓This is a group meeting with three people. (Or: This is a one-on-one between two of us.)

    One-on-one by definition involves exactly two people. If there are three or more, it is not a one-on-one.

Other forms(2)

  • one-on-one noun

    "I scheduled a one-on-one with my engineering lead."

  • one-on-one adjective

Questions(5)

What is the purpose of a one-on-one in tech companies?
One-on-ones serve several purposes: providing and receiving feedback, discussing career growth and goals, addressing concerns or blockers, building rapport between manager and employee, and aligning on priorities. They are a key tool for communication and development in tech teams.
How often do you have one-on-ones?
Most tech companies schedule one-on-ones weekly or bi-weekly, typically lasting 30 minutes to one hour. The frequency and duration depend on the relationship and organizational culture. Some teams also have ad-hoc one-on-ones as needed.
Is one-on-one formal or informal?
One-on-one is neutral in formality. The term itself is neither very formal nor very casual, though one-on-one meetings can be either formal (like a performance review) or informal (like a casual check-in). The context determines the tone.
Can one-on-one be used as a verb?
No, one-on-one is a noun, not a verb. You do not 'one-on-one' something. Instead, use phrases like 'have a one-on-one', 'schedule a one-on-one', or 'hold a one-on-one'.
What should you prepare for a one-on-one?
For a one-on-one, it is helpful to prepare a short agenda or talking points. As a manager, think about feedback to share and goals to discuss. As an employee, prepare any questions, updates on your work, or topics you want to discuss.
