Germanium 2018

Start date: July 21, 2018, 5 p.m. UTC
You have a deck of cards in which each card has two numbers: one on the front and one on the back. Flip some cards over so as to maximize the smallest integer that's not present on any card's front.

MOVE FAST. TAKE RISKS. STRIVE FOR IMPACT.

At Europe's largest fashion platform, we scaled our tech to serve over 22 million customers in 17 markets, while keeping to our engineering values and culture. We are over 1500 engineers driven by enthusiasm to improve our work, even when it means reshaping the status quo.

“Your attention to detail and a proper understanding of time/space complexity and the ability to problem solve will get you through the Germanium Challenge. I chose this task as the effective use of basic data structure and ability to correctly reason about algorithms is a crucial skill when it comes either to building reliable services and/or working with larger sets of data – key tasks for the day-to-day work at Zalando.”

– Jiri Syrovy, Software Engineer at Zalando
