How long should video interview answers be?
Use the employer's limit, and plan to stop a little before it. A finished short answer beats a cut-off long one.
The limit is the employer's, not a universal rule
One-way platforms let each employer set the answer length per question. A common range is 1 to 3 minutes. Some video questions, especially inside broader assessments, are closer to 60 or 90 seconds. If your invitation lists a time, practice at that time. If it does not, you will see the countdown on the interview screen before you record.
Stop before zero
Treat the limit as a wall, not a target. For a 2-minute answer, aim to finish around 1:45. For a 90-second answer, aim for about 75 seconds. You need room for the last sentence. Being cut off removes the result, which is the part that makes the story make sense.
A rough word budget
People speaking clearly in an interview land around 120 to 140 words per minute, sometimes slower when they are thinking. A two-minute answer is often 200 to 240 words if you leave a buffer. A 90-second answer is closer to 140 to 160 words. If your practice transcript is much longer than that, you are rushing or you are not going to finish.
What to cut first
Cut the preamble and the extra context. Keep the task, two actions, and the result. A second example almost never fits. If you have 60 seconds, you get one action and one result. Say them plainly.
"Tell us about yourself" is shorter than a story
That answer is often best at 60 to 90 seconds even if the timer allows more. Present, past, future. Then stop. Filling the entire timer with biography makes the next questions harder, because you are already tired and you have used stories you needed later.
