Presentation Tips From Interviewers

You've built the content, now it's about how you deliver it. These tips come straight from interviewers and coaches at OpenAI, Ripple, Cognition AI, and LangChain.

Expect to be stumped

Interviewers deliberately ask a "why" question you haven't prepped for, specifically to see how you handle being caught off guard. Most technically strong candidates struggle here.

Why do interviewers do this? It mirrors a real skill FDEs need on the job: when talking to a customer, it's often better to say you don't know and circle back than to guess and get it wrong.

Practice a calm, honest "I don't know, here's how I'd find out".

Be excited

It's the project you chose to present. If you don't convey genuine excitement about it, you can’t expect interviewers to be excited about it either, which makes the conversation much less engaging for both parties.

Instead, think of it as showing off something cool you built to fellow engineers, specifically those who might want to borrow your idea for their own work.

Don’t use a script

Interviewers can immediately tell when a candidate is reciting AI-generated content or reading straight off a PDF or slide deck, especially now that scripts are this easy to produce. Doing that in this round is a disqualifier.

If you've gone through the previous lesson, trust that you already have the talking points. Approach this as a conversation.

Do at least one mock presentation

Since you're not working from a script, you need to talk through the presentation enough times that it feels natural.

It's the best way to shake off pre-interview jitters, and the best way to surface follow-up questions you haven't thought of yet.

After a couple of solo run-throughs, do the whole round with an engineering peer.

If you're strapped for time or can't schedule it with a peer, do it with AI.

Paste this prompt as text first:

Act as an engineer who wants to implement something similar to what I'm about to present. Ask genuine follow-up questions as I walk you through it, including ones that catch me off guard, the way a real curious engineer would.

Once the AI has it, switch to voice mode and present out loud from there.
