Heard that Stripe requires candidates to build a web app as one of the interview rounds. Is this true? Do I need to be familiar with the web server libraries in my chosen language before the interview?
It’s not quite that grandiose, but I guess you can stretch it to mean that. It’s completely reasonable, don’t worry. You can google stuff you don’t know how to do, so you’ll be fine.
No but it may involve debugging one!
The debugging is the best round! It’s a fun interview, I have to say.
