First was an HR screening call, about my history and describing the job.

Then three interviews:

• Technical screening call, 15 minutes, general terms (what technologies have you worked with), very easy.
• Technical interview with a team member.
• Design interview at the offices.

Technical interview with a team member. Wanted to see use of Kotlin-specific functions and general OOP principles.

Design interview at the offices. Asked to design an app to manage issues, both offline and online. Handling conflicts with data on the server. Wanted to see which libraries are used and which technologies specifically.
