I applied online. I interviewed at Revolut (París) in Nov 2021
Interview
Implémentation d'un loadBalancer. La personne était arragonte et très stressé de façon qui j'étais très mal à l'aide depuis le début. Limite il était obligé de me faire l'entretien.
1 j'ai effectué le tdd et c'était ok pour lui mais il ne m'a pas laissé terminé l'optimasation du code malgré qu'il restait du temps et qu'on a commencé 5 min en retard.
2 Il m'a rapproché que j'ai eu difficulté à initialiser un set hors ce n'est pas vrai j'ai juste oublié mais j'ai peu le faire en 5 secondes max.
3 une question sur pourquoi j'ai utilisé set et pas une liste, j'ai mal répondu.
4 il m'a rapproché de manque d'utilisation des features java parce que je n'ai pas utilisé contains ou indexof hors je connais mais je sais aussi que ça fait 2 boucles for au lieu d'une j'ai préferé mon implémentation.
5 weired instantiation selon lui parce que je l'ai fait dans la méthode au lieu du constructeur, j'ai lui donné l'explication qu'on gagne une case mémoire comme on a pas besoin au début, au contraire ça montre que je sais comment la stack est utilisée...
- sur le tdd j'ai voulu être perfectionniste je suis allé plus loin en faisant le test même sur chacune des instances "la contrainte était 10 instances max" alors j'ai oublié que mon loadbalancer persiste tous donc il avait déjà 1 instance de mon premier tester, la comparaison échoue alors. Ça remarque était que la 11 qui ne va marcher pas la 10. Monsieur de 0 à 9 c'est 10 et oui j'ai comparé les 10 premiers avec 10 différents pour ça cela ne marche pas. Ni moi ni toi on a pu voir ça seulement je l'ai remarqué en sortant.
Bref que des remarques subjectives avec une personne qui n'a pas le niveau pour évaluer vos compétences.
Interview questions [1]
Question 1
implémenation d'un loadbalancer avec 10 instances max
I applied through a recruiter. I interviewed at Revolut
Interview
The experience was disappointing and reflected a lack of professionalism.
The interaction gave the impression of a disorganised or potentially unhealthy work culture.
Answered most of the questions accurately and to the best of my ability.
The interview was initially scheduled for a short time slot. Toward the end, the interviewer asked for my availability and indicated that they would schedule a follow-up session to continue the discussion. However, no further communication or follow-up was received.
I applied online. The process took 5 days. I interviewed at Revolut in May 2026
Interview
During the initial HR screening call, the recruiter explicitly stated that Revolut was not hiring for a specific team and that team fit would be determined only after the coding and system design stages.
However, after passing the screening, I received the following rejection message: “After carefully reviewing your experience, we've decided to move forward with candidates whose profiles more closely align with the specific requirements of the role. Please note that this decision is based on current team needs.”
This creates a clear inconsistency in the communication. If team allocation and specific requirements were to be evaluated only in later technical rounds, a rejection citing “current team needs” right after screening appears contradictory. Such practices can lead to candidates investing time in the interview process based on incomplete or misleading information at the early stage.
I applied through a recruiter. I interviewed at Revolut (Dubai) in May 2026
Interview
Interview begins with recruiter calling, explaining you the process
- Coding round
- System Design
- Hiring Manager round
- Bar raiser round
Each rounds are qualifier to another round. I did the coding round and system design, and I was ruled out
Interview questions [2]
Question 1
Coding round for the Matrix grid problem for 60 min coding round
First Part of the problem
- Randomly fills a matrix (a * b) with 5 'x' alphabet, reset would be 'o' alphabet
Second part of the problem (minesweeper game on Windows OS)
- Given a matrix fill with 'x', find number of minds adjacent to it
You need to solve both problems in 40 mins to qualify (First 10 mins Introduction, last 10 minutes is follow-up question)
Remember to ask follow-up questions else it mark as candidate isn't proactive in asking questions
2. System Design Round (90 mins)
They ask to design an internal developer portal that establishes a fully automated, version-control CI/CD pipeline at scale.
It basically involves designing the Internal developer, I started with requirements, non-funtional requirements, entities in system, I started with API design but they said it's okay to skip, and high level design.
I started with Component-Based Design where I drawn frontend, CLI, API Gateway, catalog services, ... and all other components of the developer portal
But they were interested in detailed CI/CD pipeline steps. This is where I screwed up; I caught the hint much later in the interview when there were 10 mins left, and I quickly drawn CI pipeline and a CD pipeline, but wasn't able to explain each step in the CD pipeline in detail.
They wanted a more comprehensive Workflow and Operational design of CI/CD pipeline instead of a component-based design of the internal developer portal.
Since I didn't complete the design, I was ruled out of the interview
