The Flatmate Interview: Questions That Actually Matter

Stop Asking 'Are You Tidy?' Ask These Instead

'So... are you pretty tidy?'

I asked this in four different flatmate interviews one summer. Every person said yes. Every person had a completely different definition of what yes meant. The problem with flatmate interviews is that everyone performs. You're speed-dating someone you'll share a bathroom with for a year, under pressure to fill the room before rent comes around. Most questions are designed to get reassurance, not information.

Here's how to actually find out what someone is like to live with.

Why the Standard Questions Fail

TradeMe Property's flatting research consistently finds that the leading cause of serious flatmate conflict in New Zealand is misaligned expectations, not personality clashes, but assumptions that were never made explicit before the bond was paid. The interview is your only real window to close those gaps before someone moves their stuff in.

Questions like 'are you tidy' and 'are you quiet' are closed questions with obvious correct answers. Nobody in a flatmate interview admits to leaving dishes for four days. Ask better questions.

The Questions That Actually Reveal Something

'What time do you get up on weekdays versus weekends?' This tells you more than 'are you a morning person?' If they're up at 5:30 AM on Saturdays and you're regularly up at 11, you can coexist — but only if you're both honest about noise and bathroom timing.

'How did you handle bills with your last flatmates?' Listen for systems, not sentiments. 'We just sort of figured it out' usually means one person managed everything and the others drifted. 'We had a shared account and split things monthly' suggests someone who understands the admin side of flatting is part of being a decent flatmate.

'What's your worst flatmate habit?' A brilliant question. 'I leave dishes soaking overnight but always do them before work' is honest and manageable. 'I honestly can't think of anything' means either low self-awareness or a performance — both are warning signs. Willingness to be mildly honest in an interview is a reliable signal of how someone handles conflict in a flat.

'How often does your partner or friends stay over?' Not 'do people visit' — everyone says occasionally. Push for frequency. A few nights a week can mean a de facto extra flatmate using the bathroom, kitchen, and hot water while contributing nothing to the power bill.

'What did you like least about your last flat?' If they say 'my last flatmate never cleaned the stovetop' and your current flat habit is not cleaning the stovetop, you've learned something genuinely useful before committing to anything. It also reveals how they talk about other people.

Red Flags During the Viewing

•        Do they ask questions back? A one-directional interview can signal disinterest or an assumption they're doing you a favour.

•        Do they only describe previous flatmates as problems? The person whose stories always feature other people as the villain is often the common thread.

•        Are they in an unusual rush to move in? Sometimes it's a lease ending — sometimes the last situation ended badly enough they need out fast.

•        Are they actually looking at the flat, or just going through the motions? The person who asks about storage and hot water is planning to live there.

What You're Actually Looking For

The benchmark isn't 'could I tolerate this person for 12 months.' That's survivorship thinking. The real question is: does this person's presence in the flat feel neutral to positive? Would you voluntarily spend twenty minutes with them in the kitchen on a Tuesday evening?

You're not looking for a best friend. You're looking for someone whose default setting in a shared space is consideration rather than obliviousness. These questions are designed to surface that before you've handed over a bond.

One final note: the person who seemed slightly awkward but answered every question with genuine honesty is often a better long-term bet than someone who was polished and told you exactly what you wanted to hear. Performed ease in an interview doesn't translate to actual ease in a flat.
