I applied online. The process took 6 weeks. I interviewed at Zettle in Dec 2018
Interview
It all started with phone interview, we were talking about my motivation, background and interests, also some Android related questions that were focused on Android trends.
After that, Tech Interview followed. It consisted of CS questions (multithreading, networking, oop,...), LiveCoding (roll the dice) and then Code review of someones code.
After that followed 2nd technical interview it was more focused on system design.
4th round was Tech Manager interview we're mainly talking about their teams structure, how they work and asked about how I work.
5th round was Cultural fit interview where we were talking about me, make sure you show your initiative :)
Generally company had good vibe, I like tech stack and how teams are organised also their code culture. Whole process was done remotely.
