I did something stupid. I lied in the standup and then they asked me for showing my results.

ngl, I cringed a bit from reading this 😬. The good news is that the first step is being self-aware, and you're doing that now!

As you have certainly figured out by now, honesty is the best policy. I would apologize to the team saying that you weren't nearly as close to being done as you initially thought and you'll need X amount of time (a few days, a few weeks, whatever it is) to finish and have a demo everyone can be proud of.

This is a very awkward topic, but that also means it's a great thing to talk about in the next 1 on 1 with your manager. You can apologize again personally there and talk more about how to resolve this issue.

On top of that, I recommend looking back and reflecting. Why did you choose to lie in standup?

• Everyone else on your team is crushing it and you feel pressure to perform?
• This task has been behind for a while now and you just want to be able to finally say that it's done?
• The initial estimate you gave for the task was a wild underestimate?

If it's the peer pressure one, I recommend this: "How do I not compare myself to others in my career?"

If it's a timeline/poor scoping out issue, I recommend these:

• https://www.jointaro.com/course/level-up-your-code-quality-as-a-software-engineer/break-it-down/
• "How do I create proper timelines and roadmaps for my projects?"

Say something like "I misinterpreted the completion criteria and I'm actually not done"

This gives you a way to save face and is conceivably true -- there are varying definitions of "task completion".
