Should I send a thank-you note after a UK interview?

From the recruiter side: I receive thank-you emails after roughly half the interviews I run. The candidates who send a thoughtful one-paragraph thank-you within 24 hours are remembered slightly more positively. It's not the deciding factor in any single decision, but in close calls between two candidates of similar merit, the small advantage adds up.

What works. Three sentences, max 80 words. First sentence: brief thanks for the time. Second: one specific thing from the conversation that resonated, ideally something that ties back to your fit for the role. Third: restated interest in moving forward. 'Hi [name], thank you for the time today. The conversation about how the platform team is rebuilding around event-driven architecture really crystallised why this role interests me — that's exactly the kind of work I've been wanting to do at scale. Looking forward to hearing about next steps.' That's the entire email.

What not to do. Don't write a paragraph. Don't recap your CV. Don't argue points where you felt the interview went badly ('I wanted to follow up on the question about distributed systems — what I meant to say was...'). Don't flatter ('what an incredible team you have'). Don't ask urgent questions ('when can I expect a decision?'). All of these reduce the signal of the thank-you rather than enhancing it.

Send within 24 hours, ideally within 2-4 hours of the interview while you still remember specifics. If you wait three days, the follow-up reads as routine rather than engaged. If you send it within the first hour, it can read as performative; aim for the same-day-but-not-immediate window.

Address it to the most senior person in the interview, copying anyone else who interviewed you in the same session. If you had a panel of four, one email addressed to the panel chair is fine. If you had a sequence of separate interviews across the day, a brief email to each is better than one long composite — but each can be ultra-short, even just two sentences.

If you don't have email addresses for the interviewers, send the message via the recruiter and ask them to forward. Most recruiters do, immediately, because it makes them look organised to the hiring panel. 'Could you forward this to [interviewer names] when you get a chance? Thanks.' That's all.

Cultural notes. UK convention is more reserved than US — keep the email less effusive than American templates suggest. 'Thank you' and 'looking forward to hearing about next steps' is the right register. 'Excited' and 'absolutely thrilled' both read as American import in UK interviews and can feel try-hard. Match the tone of the interview itself; if it was conversational, the thank-you can be too; if it was formal, keep the email formal.
