System Design Interview:

You're building an e-commerce platform.

A customer places an order.
Payment succeeds.
The order is created.
A confirmation notification is sent.
But the notification service crashes before delivering it.
The customer is charged but never receives confirmation.
No error is shown.
No alert is triggered.

How would you design the system to handle this failure and ensure the order is processed reliably?

Saturday went well! 🔥
Best progress I've had so far.

Hope this momentum continues. 🚀

I've solved 300+ CF problems, but I'm still struggling to solve even 2 problems consistently in contests.
I feel like I'm doing something wrong, but I can't figure out what it is.

If you've been in a similar situation, what helped you break through? Any advice would mean a lot🙏

[Sahil Sahu @Sahil_Unique23]

Finally solved those 2 problems that dropped my rating by -39 😭

Brooohhhh, my rating has been going down for the last 4 contests 💀

Now, only upsolving can save me. 😭

Did you upsolve questions of CF Educational Round 193?
