Advent of Code 2022
Catawiki raffle
Catawiki is happy to be sponsoring Advent of Code 2022.

Advent of Code is an Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like. Every day from 1st to 25th December, there are two challenges. For each challenge you solve, you’ll be rewarded with 1 star.

We’ve set up a few private leaderboards for this challenge, where you can compete and hopefully win a prize through our raffle!

The skills required for this challenge are similar to those used by our Tech team at Catawiki to solve some complex development tasks that result from our continually increasing numbers of sellers and buyers (in 2021 over 1 million people placed a bid on one of the objects submitted by our 200,000 sellers worldwide). We’ve already implemented localisations for various European countries and we’ll be expanding even further, outside of Europe, in the near future.
