Interview questions [1]
Question 1
finding the position of an element in a sorted list
I applied in-person. The process took 5 days. I interviewed at Zalando in Aug 2016
Interview
The first round of the interview process was a skype interview with one of Zalandos recruiters. It was a very friendly chat where we covered some basic questions (salary expectations, possible start). Nothing related to the real topic. It took approximately 45 minutes.
I got an email the next day with a positive feedback so there will be two more rounds. Next is 1.5 technical interview with coding test.
