I applied online. The process took 2 weeks. I interviewed at Revolut (Dubai) in Jun 2024
Interview
First a phone screening with a Recruiter. Second was a live coding interview which was easy. The task was to implement a java program that simulates a URL shortener. I say "simulate" because you obviously don't have time, given the 60 minutes, to implement a full-blown url shortener. The objective here is not to be able to build a real URL shortener, but to be able write clean, maintainable, and tested code under pressure.
Interview questions [1]
Question 1
What does ACID stand for? Name the database isolation levels.
HR -> Live coding -> Tech -> System design
Overall the before starting the recruitment process it's worth mastering concurrency, DB(especially PostgresSQL), and transaction management. Company seems to be working mostly with Java, Kotlin and a little with Scala
I got contacted by a recruiter. As a first step, I had a call with another recruiter. He was also asking technical questions, but it felt strange. (A bit like talking to a wall.)
I was rejected with a generic message stating that I was not "aligned with the position". This is weird as it was inbound and based on my profile. No feedback, of course.
Waste of time.
Very kind. The questions weren’t easy, but with knowledge of database configurations, concurrency, locks, and some practical experience, you are able to answer them clearly, confidently, and effectively overall. It was good time.
