Structured Feedback and Peer Interview Practice
Feedback improves performance only when it is specific and task focused. The evidence, and how to make practice with a partner actually move your score.

Practising with a colleague is one of the oldest pieces of interview advice, and one of the most wasted. The usual session ends with "that sounded really good", which is kind, costs nothing, and changes nothing. The feedback literature explains why, and it points at a fix that is easy to build into every practice session.
Feedback helps, but not always
The largest meta-analysis in the field, by Kluger and DeNisi, found that feedback improved performance on average, but that over a third of feedback interventions actually made performance worse. The pattern behind the failures is consistent: feedback that draws attention to the person ("you seemed nervous") rather than the task tends to harm; feedback anchored to the task and how to do it better tends to help.
Hattie and Timperley's influential review puts the useful kind into three questions: where am I going, how am I going, and where to next. Applied to an interview answer, that means the criteria being aimed at, what the answer did against those criteria, and the specific change for the next attempt. "Sounded good" answers none of the three.
A mark scheme changes what a partner can see
The practical fix is to give the person listening something concrete to listen for. Scoring rubrics are studied for exactly this reason: reviews such as Jonsson and Svingby's find that rubrics tend to make judgements more consistent and make expectations visible to the learner. With a mark scheme in hand, an average colleague becomes a useful interviewer: they stop judging your general impression and start ticking whether you named the discriminating points.
- Anchored: every comment traceable to a criterion, not a vibe.
- Specific: the phrase or omission that cost the mark, quoted back.
- Forward looking: one or two changes for the next run, not ten.
- Task level: about the answer, never about the person.
The station, interviewer view
A 32-year-old woman attends clinic worried about a changing mole on her forearm. You are shown a photograph. How would you approach her? Release the follow-ups as your partner goes.
Running a session that works
- 1Pick a station with a mark schemeThe listener needs criteria in hand before you start, not an impression to reconstruct afterwards.
- 2Interviewer reads the criteria firstTwo minutes reading what a strong answer contains turns a colleague into an interviewer.
- 3Run it timed, ticks liveAnswer aloud against the clock while your partner ticks what they actually hear, not what they assume you know.
- 4Debrief from the ticks, then swapThe unticked lines are the feedback. Agree one or two changes for the rerun, write them down, and change seats.
Interviewing your partner is also preparation
Reviews of peer tutoring, notably Topping's, report benefits on both sides of the table. Marking a colleague against criteria forces you to hold the mark scheme in working memory, hear what a strong answer sounds like from the outside, and notice the habits you share. Swap roles halfway through every session: the interviewer seat is not the rest break, it is the second half of the training.
How TheatrePass helps
The Prep Lounge pairs you with another candidate on a live video call and puts the station, its follow-up questions and its authored mark scheme in front of whoever is interviewing, grouped by the official scoring domains. The interviewer ticks as you answer, and the ticks become a written report you keep, so peer practice ends with the same kind of structured, criterion-based feedback the evidence supports rather than a warm impression.
