Explain the timer before it starts
A timer can help a candidate plan an answer or it can make the format feel like a test of speed. The difference can be in the explanation. Tell the candidate whether the timer covers the question, the preparation and the answer, or only the recording. Show where the time appears on the screen and what happens when it reaches the end.
Put the rule in the invitation and repeat it on the screen before the question. A candidate should not learn the timing from a countdown that starts without warning.
Offer a practice step
When the employer has enabled an unscored practice question, tell the candidate that the practice answer is not reviewed. The practice step lets the candidate see the camera, hear the microphone and get used to the screen. Keep it short and give the candidate a way to skip it.
If there is no practice question, offer a device check before the interview. The candidate can test the camera and the connection without recording an answer. The purpose is to remove the technical surprise, not to add another task.
Give a simple answer structure
Candidates can lose time because they are not sure how to start. Give a short structure in the invitation: the situation, what the candidate did, what happened and what they learned. The candidate can prepare a few examples in that shape before the interview.
Keep the structure optional. A candidate with a different way of organizing an answer should not be penalised for using it. The structure is a help for planning, not a template the reviewer scores.
Explain retakes and think time
If the employer allows a retake, say how it works. Does the new attempt replace the old one, or does the reviewer see both? Is there a limit? A candidate who knows the rule can decide whether to use an attempt or keep the answer.
If the screen shows a think time before the recording, explain it. The candidate can use the pause to read the question and choose an example. A think time that appears without explanation can feel like a delay or a fault.
Make the support route visible
Put a contact on the interview screen and in the invitation. Say who answers and what the candidate should include: the question number, the device and a short description of the problem. A candidate who can reach a person does not have to solve a blocked screen alone.
If the candidate loses the connection, explain what happens to the answer. Is it saved, can the candidate resume, and who should they contact? A clear rule turns a moment of panic into a practical next step.
Ask candidates what caused the pressure
After a round, ask a few candidates which part of the format made them hesitate. The timer, the instructions, the device check or the retake rule may be the source. Fix the part that caused the pause and keep the assessment criteria unchanged.
A timed interview is a format, not a character test. Clear rules, a practice step and a simple structure give the candidate a fair chance to show how they think. That is the part the reviewer needs to see.
