I applied online. The process took 2 weeks. I interviewed at Revolut (León, Castile and Leon) in Oct 2021
Interview
Somebody reached over LinkedIn and I replayed back. Two days later, I had a call with an HR representative who sent me some coding exercises to do online using HackerRank.com
After that, you get a 2 hours coding interview and if you pass, you finish with a 30 minutes call with the iOS lead of the company.
Interview questions [3]
Question 1
HackerRank.com exercises:
- Online Hackerrank question: Given an integers array, find the powers of two.
- Online Hackerrank question: Given an integers array, find the smallest absolute difference between its items and print the dupes.
In the second interview, he asked me to share my screen and do some coding with Xcode. It was fairly simple and if you have at least 3 years of iOS experience you won’t have any big problems. Make sure you remember how to do sync, async code. They really care about you being able to manage async code.
Lastly, I had a different call with the IOS. It was really informal and we talked about my working experience and some basic iOS knowledge. I didn’t like the guy was not really listening to my answers and he was cutting me off all the time.
I applied through a recruiter. I interviewed at Revolut (Madrid) in Oct 2025
