Founder here. Most people answer "tell me about yourself" as a resume recap, and it costs them the room
I run a career platform, so I spend a lot of my week looking at how people talk about their own work. "Tell me about yourself" is the question I watch go wrong the most, and it goes wrong the same way almost every time.
Most people treat it as a cue to recap the resume in order. They start at the first job, walk forward year by year, and land in the present a little out of breath. The interviewer already read the resume. What they're actually doing during that first answer is deciding what kind of story to listen for, and a chronological list hands them nothing to hold onto.
The fix is to answer with a throughline instead of a timeline. Pick the one thread that explains why you're sitting in that specific room, and let two or three points from your history hang off it. Something like: "I'm the person who gets handed the messy, undefined problem and turns it into something a team can actually ship. That's the thread through my last two roles, and it's why this one caught my eye." Then you stop.
That version does the interviewer's work for them. It tells them what to dig into, and it makes you sound like someone who knows what they're good at instead of someone reading their history back.
