Try it: A teammate keeps interrupting you
For the third meeting in a row, your teammate Dana has cut you off mid-sentence and finished your point as hers. The meeting just ended and you are both packing up. Address it with her directly.
That is the third time this week Dana has talked over you and landed your point as her own. The room is emptying out. You have a short window with her one-on-one, and the easy move is to let it slide again. Do not.
Say your answer out loud first if you can, then type what you said. Most strong answers are about 80 to 150 words (3 to 4 sentences).
That was the third meeting this week where Dana cut you off mid-sentence and landed your point as her own. The room is emptying out. You have a short window with her one on one, and the easy move is to let it slide again.
Name the pattern with a number, describe what it costs you, and ask for one specific change. That is how to tell a coworker to stop interrupting you without it turning into a standoff. Not a sigh. Not a joke about it. A calm, factual sentence, said privately, that gives Dana something concrete to change.
The reason this is hard is that a single interruption feels too small to raise. And it is. The problem is never one interruption. It is the fourth, the tenth, the meeting where your manager credits Dana for an idea you started saying out loud before she finished it for you. By then you have trained the room to expect that your sentences belong to whoever talks loudest.
There is also a fear that naming it makes you look thin-skinned. It does not, as long as you keep it about the behavior and the cost, not about Dana being a bad person.
Run the conversation below before you have the real one. The sim drops you into the moment right after the meeting.
Why naming the pattern beats reacting in the moment
A product manager at a fintech startup in Austin told me she spent two quarters getting steamrolled in standups by a peer who finished everyone's sentences. She kept trying to fix it live, talking faster, louder, which only made her sound frantic. Then she caught him after a Tuesday standup and said one thing: 'I have been cut off before I finish in the last four standups. I need to land my own points.' He had no idea he was doing it. It mostly stopped.
Most chronic interrupters are not malicious. They are excited, or anxious, or they process out loud. That does not make it your job to absorb it, but it does mean a calm, direct heads-up usually lands, because you are giving them information they genuinely did not have.
What to actually say, word for word
Lead with the pattern and a number. 'In the last three meetings, I have been cut off before I could finish a point.' The number makes it a pattern, not a one-off you are blowing up. It also makes it hard to wave away with 'I don't think I do that.'
Then name the cost, briefly. 'A couple of times the idea landed as yours before I had finished making it.' You are not accusing her of stealing. You are describing what actually happens. Keep it to one sentence so it does not tip into a list of grievances.
Make the ask specific. 'Going forward, can you let me finish the thought before you jump in.' Not 'can you be more considerate,' which she can nod at and change nothing. A concrete behavior gives her something she can actually do differently on Monday.
If she gets defensive, do not argue about whether it happened. 'I might be wrong about how often, and either way, letting me finish would help a lot.' You concede the count, not the request. That keeps the conversation on the fix instead of a debate about her intentions.
The mistake that undoes it
The biggest one is wrapping the whole thing in apology. 'Sorry, this is probably nothing, I hate to even bring it up, but maybe sometimes.' Six hedges in, Dana has learned this is not important and she can ignore it. Say it plainly. 'I have been cut off in the last three meetings and I need to finish my own points' is not rude. It is clear.
How to close it
End warm and forward-looking. 'I really value working with you, I just want to be able to finish a thought in the room.' That sentence tells Dana this is not a referendum on her, it is a small, specific ask from someone who wants to keep working well together. Most of the time, that is all it takes. The people who cannot figure out how to tell a coworker to stop interrupting them are usually not short on words. They are waiting for permission to use 30 uncomfortable seconds to fix a problem that is costing them a lot more than that.
