Senior Android Developer Interview Experience

October 1, 2025

Positive ExperienceNo Offer

I've gone through 3 interview processes:

Coding challenge (MCQ, 1 problem-solving (easy))
A tech interview (where they give you a specific task project and ask you to continue with some points)
A system design interview (with a focus on mobile design, but goes to the backend for on-surface knowledge)

They've asked about HashMap's performance and some MCQs related to Android in the first coding assessment.

The following metrics were computed from 8 interview experiences for the Revolut Senior Android Developer role.
