I applied through a recruiter. The process took 1 week. I interviewed at Tuenti
Interview
Two phone interviews, one with the HR person and other was more technical.
After that, there is a technical test for which you have to write some code that you'll send to them afterwards. The test is slightly complicated.
Interview questions [1]
Question 1
Java specific questions. Differences between final, public, private and friendly, differences between a list and a set and a list and an array, etc.
