You got the calendar invite at 4pm. The interview is tomorrow morning at 10. That’s roughly 18 hours, minus sleep, minus the hour you’ll spend being anxious before bed.
Here’s the thing: 18 hours is actually enough. Not enough to become an expert in the company’s entire product history. Enough to walk in with answers that land.
The problem most people run into is spreading that time too thin. They spend three hours reading the company’s blog, then cram 50 behavioral questions at midnight, then try to sleep. Scattered prep is worse than focused prep, almost always.
This is a real plan. Work through it in order.
The first two hours: figure out what the company actually does
Not their mission statement. What they actually sell, to whom, and why someone buys it.
Go to the website and read the pricing page. Pricing pages tell you more about a business than any “About Us” ever will. Then read their most recent press release or blog post (check their newsroom). Then skim one earnings transcript or one recent TechCrunch or Bloomberg article about them.
You’re looking for five things: what they sell, who their main customers are, what the business model is, what they’re stressed about right now, and what they’re excited about. You can find all five in under two hours if you don’t get distracted.
Open a doc. Write down the five things in your own words, not copied. You’ll use this later.
Hours three and four: the questions that always come up
There are a handful of questions that appear in nearly every interview, regardless of the role. According to LinkedIn’s Talent Blog, the most common openers cluster around “tell me about yourself,” “why do you want to work here,” “describe a challenge you overcame,” and “where do you see yourself in five years.”
Pick 8 questions for your specific role (not 50). Use an AI tool to generate a focused list based on the job description. Then write a real answer to each one. Not bullet points. Full sentences you’d actually say out loud.
For behavioral questions, use STAR loosely: Situation, Task, Action, Result. The mistake most candidates make is spending 80% of the answer on situation and task, then rushing through action and result. Flip that ratio. Interviewers care more about what you did and what happened than how you set the scene.
One honest admission: I don’t know exactly how much time you need per question. It depends how fast you write and how well you know your own work history. But if a question takes you more than 20 minutes to answer in writing, that’s a signal you need to think about it more, not write faster.
Hours five and six: say it out loud, not in your head
Reading your answers silently does almost nothing for interview performance. Your brain fills gaps when you read. It doesn’t when you speak.
Record yourself answering each question on your phone. Play it back once. You’ll immediately hear the filler words, the stumbles, the places where your logic jumps around. Fix those in your notes, then record again.
This is where AI tools become genuinely useful. Tools like Craqly let you run mock interview sessions with real-time feedback on your answers, so instead of recording yourself into a void, you get some signal on whether your answers are actually coherent. It’s not a substitute for the thinking you did in hours three and four. It’s a faster feedback loop on the delivery.
Two rounds of practice per question is usually enough. Don’t do ten rounds. You’ll memorize the words instead of the intent, and memorized answers sound like memorized answers.
Hour seven: logistics
This sounds trivial. It is not trivial.
Look up the location and time the commute for the actual departure time, not an average. Check whether it’s in-person or video. If video, test your audio and camera now, not at 9:58am. Pick your outfit tonight and hang it up. Charge your laptop and your phone.
These things take 30 minutes and people skip them, then spend the remaining 7 hours doing more prep, then show up rattled because the parking garage was closed. Don’t be that person.
Before you sleep: stop preparing
There’s a real cutoff point after which more studying actively hurts you. The NIH research on sleep and memory consolidation is pretty clear: your brain processes and stores what you’ve learned during sleep. Staying up until 1am cramming displaces that consolidation window.
Set an alarm. Read something completely unrelated for 20 minutes. Sleep.
The morning
Don’t reread your notes in the Uber or the waiting room. You know what you know. The notes won’t change that in the next 47 minutes.
Show up with the company’s five-thing summary in your head, your 8 answers rehearsed at a conversational level, and some real curiosity about whether this is actually a place you’d want to spend your time. That last part isn’t advice you’ll see in most prep guides. But interviewers can tell when someone is going through motions versus actually interested in the work, and the difference comes through in the questions you ask at the end of the conversation.
If you got the invite yesterday and you’re reading this now: you have enough time. Use it well.
