Why a "casual chat" is still genuinely an interview
A coffee chat, common particularly at startups and smaller companies, is framed informally but is still a genuine evaluation moment, and treating it too casually is one of the most common mistakes candidates make. The relaxed setting is meant to lower everyone's guard for a more natural conversation, not to signal the stakes are lower.
How to prepare without over-formalising it
Prepare your key talking points and research as thoroughly as you would for a formal interview, but hold them more loosely, ready to let the conversation flow naturally rather than rigidly working through a script. Dress slightly more smartly than the stated setting might suggest, since it is easier to dress down slightly on arrival than to be visibly underdressed.
How to conduct yourself in the conversation
Stay professional and focused even as the tone feels relaxed, since oversharing personal opinions, complaining about past employers, or being too casual about your genuine interest in the role are easy mistakes to make once the setting feels informal. Let genuine personality come through, since this format is often specifically designed to assess that, but keep judgement about what to share intact.
